Multiple choice

Assertion (A) : Coefficient of Concurrent Deviations is calculated between the direction of deviations and not their magnitudes. Reason (R) : If it is desired to study the correlation between two series in a very casual manner.

  1. (A) is false, but (R) is true

  2. (A) is true, but (R) is false

  3. Both (A) and (R) are true, but (R) is not the correct explanation.

  4. Both (A) and (R) are true and (R) is the correct explanation.

Explanation

The Coefficient of Concurrent Deviations calculates correlation based only on the direction of changes (positive or negative deviations) between two series, not their magnitudes. This method is indeed used for casual correlation analysis when only the direction of change matters.
