What is validity and reliability in research examples? Suppose your bathroomscale was reset to . Whereas validity refers to the tests ability to measure what it was designed to measure. An assessment can provide you with consistent results, making it reliable, but unless it is measuring what you are supposed to measure, it is not valid. So content validity tests if your research is measuring everything it should to produce an accurate result. Construct-related validity assesses the accuracy of your research by collecting multiple pieces of evidence. Educational Psychology This is a little more complicated, but it helps to show how the validity of research is based on different findings. A measure that is valid but not reliable will consist of shots centered on the target but not clustered within a narrow range, but rather scattered around the target. (Reliability is required for validity but not sufficient by itself.) Example: in order to be valid, a driving test should include a physical driving exam, not just a theory exam.
