Question: Arrange the following in terms of increasing order of the minimum number of variables required for their computation:
A. Mean B. First order correlation C. Correlation coefficient D. Second order correlation
Choose the correct answer from the options given below:
- A.
A, B, C, D
- B.
B, A, C, D
- C.
A, C, B, D
- D.
B, D, C, A
Attempted by 10 students.
Show answer & explanation
Correct answer: C
To arrange these terms by increasing minimum variables required: 1. Mean (A) needs 1 variable to calculate the average. 2. Correlation coefficient (C) involves 2 variables to measure their relationship. 3. First order correlation (B) implies partial correlation with 1 control variable, needing 3 variables total. 4. Second order correlation (D) implies partial correlation with 2 control variables, needing 4 variables total. The correct order is A < C < B < D.
