Question: Consider the following small set of scores. Each number represents the number of siblings reported by each of the N = 6 persons in the sample:

X scores are [0, 1, 1, 1, 2, 7].

1. Compute the mean (M) for this set of six scores.
2. Compute the six deviations from the mean X – M, and list these six deviations.
3. What is the sum of the six deviations from the mean you reported in (b)? Is this outcome a surprise?
4. Now calculate the sum of squared deviations (SS) for this set of six scores.
5. Compute the sample variance, \({{s}^{2}}\) for this set of six scores.
6. When you compute why should you divide SS by (N — I) rather than by N?
7. Finally, compute the sample standard deviation (denoted by either s or SD).
