Textbook Problem

Calculate *SS*, variance, and standard deviation for the following population of *N* = 6 scores: 1, 6, 10, 9, 4, 6. (*Note*: The definitional formula for *SS* works well with these scores.)

To determine

**To find:** The sum of squared deviations, variance and standard deviation for the population of scores.

Explanation

**Given info:**

The data represents the population of scores. The scores are 1, 6, 10, 9, 4 and 6.and the population size as 6.

**Calculation:**

The general formula for mean is,

The mean for the population scores is,

The general formula of Sum of squared deviations is,

The sum of squared deviations (SS) for the population scores is,
