(2017) have tried to more subjective = more inconsistencies between people who measure, Sensitivity: depending on type of measure we use, the better able we will be to describe the It identifies whether the results are the same after repeated measures. In simple terms, if your research is associated with high levels of reliability, then other researchers need to be able to generate the same results, using the same research methods under similar conditions. There are examples of validity in day-to-day life. A researcher must test the collect data before making any conclusion. The application of a pretest can interfere with another measurement or test that follows. If you get the same response from a various group of participants, it means the validity of the questionnaire and product is high as it has high test-retest reliability.

Behavioral * - most easily observed True or False: A test that has high reliability does not mean that it will have high validity in return. Students who got failed in the pre-final exam are likely to get passed in the final exams; they might be more confident and conscious than earlier. What is an example of reliability and validity? A test that is considered reliable will show similar outcomes each time it is administered. Describe the influences of test reliability on test validity. (2022, October 10).
