Assertion (A): Central tendency is the tendency of most raters to give average ratings to all or the center of the scale.
Reasoning (R): a very high rating or a very low rating could invite questions, criticisms or explanations.
1. Assertion (A) is true but Reason (R) is false.
2. Both Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation of Assertion (A).
3. Assertion (A) is false but Reason (R) is true.
4. both assertion (A) and reasoning (R ) are true and Reason (R ) is the correct explanation of Assertion (A) - Choose the false statement.
1. Variability itself may be sometimes used in decision making.
2. The only purpose of measuring dispersion is to assess the reliability of an average.
3. Comparison of two sets of data can only be done by relative measures of dispersion.
4. A good measure of dispersion should preferably use all the items of the data
