Reliability and validity are concepts used to evaluate the qality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, (if you take the 'ACT' five times, you should get roughly the same results every time) and validity is about the accuracy of a measure (a test is valid if it measures what it is supposed to).
A reliable measurement is not always valid: the results might be reproducible but they might not be necessarily correct. But a valid measurement is generally reliable: if a test produces accurate results, they should be reproducible.
For example, let's say your thermometer was 5 degree off. It would be reliable since it gives you the same result each time but it is not valid because the thermometer was not recording the accurate/correct trmperature.
Should we always consider a reliable measure as valid? Why or why not? Provide an example.
A valid measurement instrument is always reliable, but a reliable measurement instrument may not always be valid.” *** comment on this statement please***
