As an example, if a survey posits that a student's aptitude score is a valid predictor of a student's test scores in certain topics, the amount of research conducted into that relationship would determine whether or not the instrument of measurement (here, the aptitude as they relate to the test scores) are considered valid. If you get an identical measurement twice, you can be confident you measured reliably.

These concepts are considered statistically significant in proving data in research to be able to be accepted as scientific truth. Reliability defines the high level of trust on the recorded data thus can be repeated and replicated. One estimate of reliability is test-retest reliability.
