He checks if his instruments meet the criteria for evaluation. Which of the following criteria refers to the consistency or the ability to yield the same response upon its repeated administration?A. Validity
A. Validity
B. Reliability
C. Sensitivity
D. Objectivity
Correct Answer: B. Reliability
Reliability is the repeatability of the instrument; it can elicit the same responses even with varied administration of the instrument. In simple terms, research reliability is the degree to which research method produces stable and consistent results. A specific measure is considered to be reliable if its application on the same object of measurement a number of times produces the same results.
Option A: Validity is the extent to which the results really measure what they are supposed to measure. A valid measurement is generally reliable: if a test produces accurate results, it should be reproducible.
Option C: Sensitivity is one of four related statistics used to describe the accuracy of an instrument for making a dichotomous classification (i.e., positive or negative test outcome). Of these four statistics, sensitivity is defined as the probability of correctly identifying some condition or disease state.
Option D: Objectivity in social research is the principle drawn from positivism that, as far as is possible, researchers should remain distanced from what they study so findings depend on the nature of what was studied rather than on the personality, beliefs, and values of the researcher (an approach not accepted by researchers in the critical, standpoint or interpretive traditions).
