When looking at reliability and validity and how they are related, reliability refers to the consistency or stability of test scores. On the other hand Validity refers to the accuracy of the inference or interpretations we make from test scores. Researchers have stated that, if you are going to have validity, you must have reliability but reliability in and of it is not enough to ensure validity. Participants used within your study are considered to be the population.
