1. 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
2. A psychologist interested in political behavior measured the square footage of the desks in the official office for four U.S. governors and of four chief executive officers (CEOs) of major U.S. corporations. The figures for the governors were 44, 36, 52, and 40 square feet. The figures for the CEOs were 32, 60, 48, 36 square feet.
a. Figure the means and standard deviations for the governors and CEOs.
b. Explain, to a person who has never had a course in statistics, what you have done.
c. Note the waus in which the means and standard deviations differ, and speculate on the possible meaning of these differences, presuming that they are representative of U.S. governors and large corporations' CEOs in general.
3. Radel and colleagues (2011) conducted a study of how feeling overly controlled makes you desire-even unconsciously-more freedom. In their study, 52 Canadian undergraduates played a video game in a laboratory and were randomly assigned to either:
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.
