Calculate the mean and SS (sum of squared deviations) for each of the following samples. Based on the value for the mean, you should be able to decade which SS formula is better to use.
Sample A: 1 4 8 5
Sample B: 3 0 9 4
Given info:
The sample scores are 7, 4, 2 and 1.
Calculation:
The formula of Sum of squared deviations is,
The formula of variance is,
The formula of standard deviation is,
The below table shows the computation of SS:


7  49 
4  16 
2  4 
1  1
