12. For the following scores, find the mean, median, sum of squared deviations, variance, and standard deviation:

1,112; 1,245; 1,361; 1,372; 1,472
Mean:
M= (( = 6,562 = 1312.4 N 5

Median: 1,361

Sum of squared deviations:
((X-M)2 or SS
(1,112-1,312.4)2+ ((1,245-1,312.4)2 + (1,361-1,312.4)2 + (1,372- 1,312.4)2 + (1,472-1,312.4)2 = 76,089.2

Variance:
SD2 = SS = 76,089.2 = 15,217.84 N 5

Standard deviation:
SD = √SD2 = √15,217.84 = 123.3606

The disparity of square footage of the desks belonging to CEOs is much wider than U.S. governors.

a. an automony deprivation condition, in which they were told to follow instructions precisely, constantly given instructions over a loudspeaker, and carefully observed on everything they did. b. a neutral condition, which was much more laid back.

After this activity, they were asked to do a “lexical decision task” (a standard approach for measuring unconscious responses) in which they were shown a series of words and nonwords in random order and had to press “C” if it was a real word or “N” if not. Half of the real words were related to autonomy (e.g., freedom, choice) and half were neutral (e.g., whisper, hammer). The key focus of the

More moderate test-retest correlations found by other studies have also indicated CDI to have higher short-term…
