Identify the correct sequence of steps used for Sandler's A-test:
(A) Subtract the hypothesised mean of the population µH from each individual score Xi

(B) Find Di

(C) Square each Di

(D) Obtain the sum of each squares

Choose the correct answer from the options given below:

Correct option is C

The correct sequence for performing Sandler's A-test is:
1. (A) Subtract the hypothesized mean (μH\mu_HμH​) of the population from each individual score (XiX_iXi​) to calculate the deviation (DiD_iDi​).
2. (B) Find DiD_iDi​, the deviation values.
3. (C) Square each DiD_iDi​ to remove negative signs and emphasize larger deviations.
4. (D) Obtain the sum of these squared deviations to determine the total variability accounted for by the differences.
This sequence ensures a systematic approach to comparing individual scores against the hypothesized mean, making it a critical statistical test for hypothesis validation.
