What is SS, the sum of the squared deviations, for the following population of N = 5 scores? Scores: 1.9,0,2,3

  1. a. 10
  2. b. 41
  3. c. 50
  4. d. 95

To determine

To find: The sum of squared deviations for the population scores.

Explanation of Solution

Given info:

The population scores are 1, 9, 0, 2, and 3.

Reason for correct answer:

Calculation:

The mean for population scores is,

μ=xiN=1+9+0+2+35=155=3

The sum of squared deviations for population scores is,

SS=(xiμ)2 </
