Textbook Problem

Calculate the mean and SS (sum of squared deviations) tor each of the following samples. Based on the value for the mean, you should be able to decide which SS formula is better to use.

Sample A: 1 4 8 5

Sample B: 3 0 9 4

To determine

**To find:** The mean and sum of squared deviations for the sample A and B.

Explanation

**Given info:**

The data represents the values of sample A and sample B. The sample A is 1, 4, 8, 5 and sample B is 3, 0, 9, 4.

**Calculation:**

*Sample A:*

The general formula for mean is,

The mean for the sample A is,

Thus, the mean for the sample A is 4.5.

The general formula for Sum of squared deviations is,

The Sum of squared deviations for the sample A is,

Thus, the Sum of squared deviations for the sample A is 25
