Question

In regards to measuring research variables, which area of measurement must be taken care of first before any other area O Objectivity Validity Reliability

Answer 1

Ans) Objectivity

Explaination:

- Objectivity is the broadest and thus is the outermost ring on the target. A test that is objective measures without reference to outside influences. For example, an objective test of personality will return the same answers regardless of whether the person completing the test uses a pen or pencil. Irrelevant, unrelated factors do not influence the test results if a test is objective.

- The middle ring on our target is reliability. Before reliability can be considered, a test or assessment must first be objective. Objectivity is essential but not sufficient to ensure reliability. There are different types of reliability, but at its simplest, reliability is repeatability. A reliable measure is one that returns the same result each and every time.

- Validity is at the center of our target. As with any bull’s-eye, it is the most difficult to hit. A test must be both objective and reliable before its validity can be considered. Validity is the extent to which the test measures what it claims to measure.
