Reliability is: a. a matter of ensuring that the measure measures what one thinks it should measure

c. a matter of whether a particular technique, applied repeatedly to the same object, would yield the same results each time

Explanation:

In social sciences, the degree for which a instrument of measuring yields the same result every time that is emplyed, once we assume that the object being measured remains constant or shows almost no change is called reliability.

The reliability coefficient results as a correlation between two or more variables that measure the same thing. Traditional methods to estimate test reliability in behavioural research are: test-retest reliability, and internal consistency,etc.

Reliability is  key in every studie since it is the degree to which an assessment tool produces stable and consistent results.

Some major types  of ways for assesing reliability are: Test-retest reliability as a measure of reliability obtained before administering the same test twice over time to a group.
