Final answer:

False. Reliability and validity are two different concepts in statistics. A test can be reliable but not valid, and vice versa.

Step-by-step explanation:

False

In statistics, there is a distinction between reliability and validity of tests. While reliability refers to the consistency of test scores, validity refers to whether the test actually measures what it is intended to measure. Thus, a test can be reliable but not valid, and vice versa.

For example, imagine a bathroom scale that always gives you the same weight when you step on it. This would be a reliable test as it produces consistent results. However, if the scale consistently underestimates your weight by 10 pounds, then the test is not valid because it does not accurately measure your weight.
