Primary Research | Definition, Types, & Examples

Published on 15 January 2023 by Tegan George .

Primary research is a research method that relies on direct data collection , rather than relying on data that’s already been collected by someone else. In other words, primary research is any type of research that you undertake yourself, firsthand, while using data that has already been collected is called secondary research.

Primary research is often used in qualitative research , particularly in survey methodology, questionnaires, focus groups, and various types of interviews . While quantitative primary research does exist, it’s not as common.

Primary research is any research that you conduct yourself. It can be as simple as a 2-question survey, or as in-depth as a years-long longitudinal study . The only key is that data must be collected firsthand by you.

Primary research is often used to supplement or strengthen existing secondary research. It is usually exploratory in nature, concerned with examining a research question where no preexisting knowledge exists. It is also sometimes called original research for this reason.

Primary research can take many forms, but the most common types are:

  • Surveys and questionnaire
  • Observational studies
  • Interviews and focus groups
  • Surveys and questionnaires

Surveys and questionnaires collect information about a group of people by asking them questions and analyzing the results. They are a solid choice if your research topic seeks to investigate something about the characteristics, preferences, opinions, or beliefs of a group of people.

Surveys and questionnaires can take place online, in person, or through the mail. It is best to have a combination of open-ended and closed-ended questions, and how the questions are phrased matters. Be sure to avoid leading questions, and ask any related questions in groups, starting with the most basic ones first.

Observational studies are an easy and popular way to answer a research question based purely on what you, the researcher, observes. If there are practical or ethical concerns that prevent you from conducting a traditional experiment , observational studies are often a good stopgap.

There are three types of observational studies: cross-sectional studies , cohort studies, and case-control studies. If you decide to conduct observational research, you can choose the one that’s best for you. All three are quite straightforward and easy to design – just beware of confounding variables and observer bias creeping into your analysis.

Similarly to surveys and questionnaires, interviews and focus groups also rely on asking questions to collect information about a group of people. However, how this is done is slightly different. Instead of sending your questions out into the world, interviews and focus groups involve two or more people – one of whom is you, the interviewer, who asks the questions.

There are 3 main types of interviews:

  • Structured interviews ask predetermined questions in a predetermined order.
  • Unstructured interviews are more flexible and free-flowing, proceeding based on the interviewee’s previous answers.
  • Semi-structured interviews fall in between, asking a mix of predetermined questions and off-the-cuff questions.

While interviews are a rich source of information, they can also be deceptively challenging to do well. Be careful of interviewer bias creeping into your process. This is best mitigated by avoiding double-barreled questions and paying close attention to your tone and delivery while asking questions.

Alternatively, a focus group is a group interview, led by a moderator. Focus groups can provide more nuanced interactions than individual interviews, but their small sample size means that external validity is low.

Primary research can often be quite simple to pursue yourself. Here are a few examples of different research methods you can use to explore different topics.

Primary research is a great choice for many research projects, but it has distinct advantages and disadvantages.

Advantages of primary research

Advantages include:

  • The ability to conduct really tailored, thorough research, down to the ‘nitty-gritty’ of your topic . You decide what you want to study or observe and how to go about doing that.
  • You maintain control over the quality of the data collected, and can ensure firsthand that it is objective, reliable , and valid .
  • The ensuing results are yours, for you to disseminate as you see fit. You maintain proprietary control over what you find out, allowing you to share your findings with like-minded individuals or those conducting related research that interests you for replication or discussion purposes.

Disadvantages of primary research

Disadvantages include:

  • In order to be done well, primary research can be very expensive and time consuming. If you are constrained in terms of time or funding, it can be very difficult to conduct your own high-quality primary research.
  • Primary research is often insufficient as a standalone research method, requiring secondary research to bolster it.
  • Primary research can be prone to various types of research bias . Bias can manifest on the part of the researcher as observer bias , Pygmalion effect , or demand characteristics . It can occur on the part of participants as a Hawthorne effect or social desirability bias .

The 3 main types of primary research are:

Exploratory research explores the main aspects of a new or barely researched question.

Explanatory research explains the causes and effects of an already widely researched question.

There are several methods you can use to decrease the impact of confounding variables on your research: restriction, matching, statistical control, and randomisation.

In restriction , you restrict your sample by only including certain subjects that have the same values of potential confounding variables.

In matching , you match each of the subjects in your treatment group with a counterpart in the comparison group. The matched subjects have the same values on any potential confounding variables, and only differ in the independent variable .

In statistical control , you include potential confounders as variables in your regression .

In randomisation , you randomly assign the treatment (or independent variable) in your study to a sufficiently large number of subjects, which allows you to control for all potential confounding variables.

A questionnaire is a data collection tool or instrument, while a survey is an overarching research method that involves collecting and analysing data from people using questionnaires.

When conducting research, collecting original data has significant advantages:

  • You can tailor data collection to your specific research aims (e.g., understanding the needs of your consumers or user testing your website).
  • You can control and standardise the process for high reliability and validity (e.g., choosing appropriate measurements and sampling methods ).

However, there are also some drawbacks: data collection can be time-consuming, labour-intensive, and expensive. In some cases, it’s more efficient to use secondary data that has already been collected by someone else, but the data might be less reliable.

They might search existing research to find the data they need—a technique known as secondary research .

Alternatively, they might prefer to seek out the data they need independently. This is known as primary research.

  • What is primary research?

During primary research, the researcher collects the information and data for a specific sample directly.

Types of primary research

Primary research can take several forms, depending on the type of information studied. Here are the four main types of primary research:

Observations

Focus groups

When conducting primary research, you can collect qualitative or quantitative data (or both).

Qualitative primary data collection provides a vast array of feedback or information about products and services. However, it may need to be interpreted before it is used to make important business decisions.

Quantitative primary data collection , on the other hand, involves looking at the numbers related to a specific product or service.

  • What types of projects can benefit from primary research?

Data obtained from primary research may be more accurate than if it were obtained from previous data samples.

Primary research may be used for

Salary guides

Industry benchmarks

Government reports

Any information based on the current state of the target, including statistics related to current information

Scientific studies

Current market research

Crafting user-friendly products

Primary research can also be used to capture any type of sentiment that cannot be represented statistically, verbally, or through transcription. This may include tone of voice, for example. The researcher might want to find out if the subject sounds hesitant, uncertain, or unhappy.

  • Methods for conducting primary research

Your methods for conducting primary research may vary based on the information you’re looking for and how you prefer to interact with your target market.

Surveys are a method to obtain direct information and feedback from the target audience. Depending on the target market’s specific needs, they can be conducted over the phone, online, or face-to-face.

Observation

In some cases, primary research will involve watching the behaviors of consumers or members of the target audience.

Communication with members of the target audience who can share direct information and feedback about products and services.

Test marketing

Explore customer response to a product or marketing campaign before a wider release.

Competitor visits

Competitor visits allow you to check out what competitors have to offer to get a better feel for how they interact with their target markets. This approach can help you better understand what the market might be looking for.

This involves bringing a group of people together to discuss a specific product or need within the industry. This approach could help provide essential insights into the needs of that market.

Usability testing

Usability testing allows you to evaluate a product’s usability when you launch a live prototype. You might recruit representative users to perform tasks while you observe, ask questions, and take notes on how they use your product.

  • When to conduct primary research

Primary research is needed when you want first-hand information about your product, service, or target market. There are several circumstances where primary research may be the best strategy for getting the information you need.

You might use it to:

Understand pricing information, including what price points customers are likely to purchase at. 

Get insight into your sales process. For example, you might look at screenshots of a sales demo, listen to audio recordings of the sales process, or evaluate key details and descriptions. 

Learn about problems your consumers might be having and how your business can solve them.

Gauge how a company feels about its competitors. For example, you might want to ask an e-tailer if they plan to offer free shipping to compete with Amazon, Walmart, and other major retailers.

  • How to get started with primary research

Step one: Define the problem you’re trying to answer. Clearly identify what you want to know and why it’s important. Does the customer want you to perform the “usual?” This is often the case if they are new, inexperienced, or simply too busy and want to have the task taken care of.

Step two: Determine the best method for getting those answers. Do you need quantitative data , which can be measured in multiple-choice surveys? Or do you need more detailed qualitative data , which may require focus groups or interviews?

Step three: Select your target. Where will you conduct your primary research? You may already have a focus group available; for example, a social media group where people already gather to discuss your brand.

Step four: Compile your questions or define your method. Clearly set out what information you need and how you plan to gather it.

Step five: Research!

  • Advantages of primary research

Primary research offers a number of potential advantages. Most importantly, it offers you information that you can’t get elsewhere.

It provides you with direct information from consumers who are already members of your target market or using your products.

You are able to get feedback directly from your target audience, which can allow you to immediately improve products or services and provide better support to your target market.

Primary data is current. Secondary sources may contain outdated data.

Primary data is reliable. You will know what methods you used and how the data relates to your research because you collected it yourself.

  • Disadvantages of primary research

You might decide primary research isn’t the best option for your research project when you consider the disadvantages.

Primary research can be time-consuming. You will have to put in the time to collect data yourself, meaning the research may take longer to complete.

Primary research may be more expensive to conduct if it involves face-to-face interactions with your target audience, subscriptions for insight platforms, or participant remuneration.

The people you engage with for your research may feel disrupted by information-gathering methods, so you may not be able to use the same focus group every time you conduct that research.

It can be difficult to gather accurate information from a small group of people, especially if you deliberately select a focus group made up of existing customers. 

You may have a hard time accessing people who are not already members of your customer base.

Biased surveys can be a challenge. Researchers may, for example, inadvertently structure questions to encourage participants to respond in a particular way. Questions may also be too confusing or complex for participants to answer accurately.

Despite the researcher’s best efforts, participants don’t always take studies seriously. They may provide inaccurate or irrelevant answers to survey questions, significantly impacting any conclusions you reach. Therefore, researchers must take extra caution when examining results.

Conducting primary research can help you get a closer look at what is really going on with your target market and how they are using your product. That research can then inform your efforts to improve your services and products.

What is primary research, and why is it important?

Primary research is a research method that allows researchers to directly collect information for their use. It can provide more accurate insights into the target audience and market information companies really need.

What are primary research sources?

Primary research sources may include surveys, interviews, visits to competitors, or focus groups.

What is the best method of primary research?

The best method of primary research depends on the type of information you are gathering. If you need qualitative information, you may want to hold focus groups or interviews. On the other hand, if you need quantitative data, you may benefit from conducting surveys with your target audience.

Primary Research: What It Is, Purpose & Methods + Examples

primary research

As we continue exploring the exciting research world, we’ll come across two primary and secondary data approaches. This article will focus on primary research – what it is, how it’s done, and why it’s essential. 

We’ll discuss the methods used to gather first-hand data and examples of how it’s applied in various fields. Get ready to discover how this research can be used to solve research problems , answer questions, and drive innovation.

What is Primary Research: Definition

Primary research is a methodology researchers use to collect data directly rather than depending on data collected from previously done research. Technically, they “own” the data. Primary research is solely carried out to address a certain problem, which requires in-depth analysis .

There are two forms of research:

  • Primary Research
  • Secondary Research

Businesses or organizations can conduct primary research or employ a third party to conduct research. One major advantage of primary research is this type of research is “pinpointed.” Research only focuses on a specific issue or problem and on obtaining related solutions.

For example, a brand is about to launch a new mobile phone model and wants to research the looks and features they will soon introduce. 

Organizations can select a qualified sample of respondents closely resembling the population and conduct primary research with them to know their opinions. Based on this research, the brand can now think of probable solutions to make necessary changes in the looks and features of the mobile phone.

Primary Research Methods with Examples

In this technology-driven world, meaningful data is more valuable than gold. Organizations or businesses need highly validated data to make informed decisions. This is the very reason why many companies are proactive in gathering their own data so that the authenticity of data is maintained and they get first-hand data without any alterations.

Here are some of the primary research methods organizations or businesses use to collect data:

1. Interviews (telephonic or face-to-face)

Conducting interviews is a qualitative research method to collect data and has been a popular method for ages. These interviews can be conducted in person (face-to-face) or over the telephone. Interviews are an open-ended method that involves dialogues or interaction between the interviewer (researcher) and the interviewee (respondent).

Conducting a face-to-face interview method is said to generate a better response from respondents as it is a more personal approach. However, the success of face-to-face interviews depends heavily on the researcher’s ability to ask questions and his/her experience related to conducting such interviews in the past. The types of questions that are used in this type of research are mostly open-ended questions . These questions help to gain in-depth insights into the opinions and perceptions of respondents.

Personal interviews usually last up to 30 minutes or even longer, depending on the subject of research. If a researcher is running short of time conducting telephonic interviews can also be helpful to collect data.

2. Online surveys

Once conducted with pen and paper, surveys have come a long way since then. Today, most researchers use online surveys to send to respondents to gather information from them. Online surveys are convenient and can be sent by email or can be filled out online. These can be accessed on handheld devices like smartphones, tablets, iPads, and similar devices.

Once a survey is deployed, a certain amount of stipulated time is given to respondents to answer survey questions and send them back to the researcher. In order to get maximum information from respondents, surveys should have a good mix of open-ended questions and close-ended questions . The survey should not be lengthy. Respondents lose interest and tend to leave it half-done.

It is a good practice to reward respondents for successfully filling out surveys for their time and efforts and valuable information. Most organizations or businesses usually give away gift cards from reputed brands that respondents can redeem later.

3. Focus groups

This popular research technique is used to collect data from a small group of people, usually restricted to 6-10. Focus group brings together people who are experts in the subject matter for which research is being conducted.

Focus group has a moderator who stimulates discussions among the members to get greater insights. Organizations and businesses can make use of this method, especially to identify niche markets to learn about a specific group of consumers.

4. Observations

In this primary research method, there is no direct interaction between the researcher and the person/consumer being observed. The researcher observes the reactions of a subject and makes notes.

Trained observers or cameras are used to record reactions. Observations are noted in a predetermined situation. For example, a bakery brand wants to know how people react to its new biscuits, observes notes on consumers’ first reactions, and evaluates collective data to draw inferences .

Primary Research vs Secondary Research – The Differences

Primary and secondary research are two distinct approaches to gathering information, each with its own characteristics and advantages. 

While primary research involves conducting surveys to gather firsthand data from potential customers, secondary market research is utilized to analyze existing industry reports and competitor data, providing valuable context and benchmarks for the survey findings.

Find out more details about the differences: 

1. Definition

  • Primary Research: Involves the direct collection of original data specifically for the research project at hand. Examples include surveys, interviews, observations, and experiments.
  • Secondary Research: Involves analyzing and interpreting existing data, literature, or information. This can include sources like books, articles, databases, and reports.

2. Data Source

  • Primary Research: Data is collected directly from individuals, experiments, or observations.
  • Secondary Research: Data is gathered from already existing sources.

3. Time and Cost

  • Primary Research: Often time-consuming and can be costly due to the need for designing and implementing research instruments and collecting new data.
  • Secondary Research: Generally more time and cost-effective, as it relies on readily available data.

4. Customization

  • Primary Research: Provides tailored and specific information, allowing researchers to address unique research questions.
  • Secondary Research: Offers information that is pre-existing and may not be as customized to the specific needs of the researcher.
  • Primary Research: Researchers have control over the research process, including study design, data collection methods , and participant selection.
  • Secondary Research: Limited control, as researchers rely on data collected by others.

6. Originality

  • Primary Research: Generates original data that hasn’t been analyzed before.
  • Secondary Research: Involves the analysis of data that has been previously collected and analyzed.

7. Relevance and Timeliness

  • Primary Research: Often provides more up-to-date and relevant data or information.
  • Secondary Research: This may involve data that is outdated, but it can still be valuable for historical context or broad trends.

Advantages of Primary Research

Primary research has several advantages over other research methods, making it an indispensable tool for anyone seeking to understand their target market, improve their products or services, and stay ahead of the competition. So let’s dive in and explore the many benefits of primary research.

  • One of the most important advantages is data collected is first-hand and accurate. In other words, there is no dilution of data. Also, this research method can be customized to suit organizations’ or businesses’ personal requirements and needs .
  • I t focuses mainly on the problem at hand, which means entire attention is directed to finding probable solutions to a pinpointed subject matter. Primary research allows researchers to go in-depth about a matter and study all foreseeable options.
  • Data collected can be controlled. I T gives a means to control how data is collected and used. It’s up to the discretion of businesses or organizations who are collecting data how to best make use of data to get meaningful research insights.
  • I t is a time-tested method, therefore, one can rely on the results that are obtained from conducting this type of research.

Disadvantages of Primary Research

While primary research is a powerful tool for gathering unique and firsthand data, it also has its limitations. As we explore the drawbacks, we’ll gain a deeper understanding of when primary research may not be the best option and how to work around its challenges.

  • One of the major disadvantages of primary research is it can be quite expensive to conduct. One may be required to spend a huge sum of money depending on the setup or primary research method used. Not all businesses or organizations may be able to spend a considerable amount of money.
  • This type of research can be time-consuming. Conducting interviews and sending and receiving online surveys can be quite an exhaustive process and require investing time and patience for the process to work. Moreover, evaluating results and applying the findings to improve a product or service will need additional time.
  • Sometimes, just using one primary research method may not be enough. In such cases, the use of more than one method is required, and this might increase both the time required to conduct research and the cost associated with it.

Every research is conducted with a purpose. Primary research is conducted by organizations or businesses to stay informed of the ever-changing market conditions and consumer perception. Excellent customer satisfaction (CSAT) has become a key goal and objective of many organizations.

A customer-centric organization knows the importance of providing exceptional products and services to its customers to increase customer loyalty and decrease customer churn. Organizations collect data and analyze it by conducting primary research to draw highly evaluated results and conclusions. Using this information, organizations are able to make informed decisions based on real data-oriented insights.
