2, 2, 0, 5,1, 4,1, 3, 0, 0, 1, 4, 4, 0,1, 4, 3, 4, 2, 1

Standard deviation: 12.65

b) We have just found the average measurements of the desks of the governors and CEOs in major US corporations. We also found the spread of the data.

c) The average, or mean of the measurements are almost the same in both cases. However, the standard deviation of the CEOs’ measurements is almost double of the governors’, which means that the CEO’s desks can be either much bigger or much smaller than the governors.

5. 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.

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.,
