validity and reliability in research example

Learn how to evaluate the quality of research methods and measures using reliability and validity. Find out the difference, types and examples of reliability and validity in research design and methods.

Reliability in research refers to the consistency and stability of measurements or findings. Validity relates to the accuracy and truthfulness of results, measuring what the study intends to. Both are crucial for trustworthy and credible research outcomes.

Learn how to assess the quality of measurements in research using reliability and validity criteria. Reliability refers to the consistency of measures, while validity addresses whether the measurements are quantifying the correct attribute.

Learn about validity and reliability within the context of research methodology. Plain-language explainer video with loads of examples.

While both reliability and validity contribute to trustworthy research, they address distinct aspects. Reliability ensures consistent results, while validity ensures accurate and relevant results that reflect the true nature of the measured concept.

Learn how to evaluate the quality of research methods and measures using reliability and validity. Find out the definitions, types, and examples of each concept, and how to ensure they in your research design and methods.

Learn the difference between reliability and validity in research, and how to assess them using various methods. See examples of test-retest, internal consistency, and inter-rater reliability, as well as content, criterion, face, and construct validity.

Reliability ensures the study's findings are reproducible while validity confirms that it accurately represents the phenomena it claims to. Ensuring both in a study means the results are both dependable and accurate, forming a cornerstone for high-quality research.

Reliability is a necessary condition of validity: a measure that is valid must also be reliable. An instrument that is properly measuring a construct of interest should yield consistent results. However, a measure can be reliable but not valid. Consider a clock that’s set 5 minutes fast.

Learn how to ensure the accuracy of your research methods and measurements with four types of validity: construct, content, face and criterion. See examples of each type and how to apply them in your research.
