Chapter 3

1. For the following scores, find the mean, median, and the mode. Which would be the most appropriate measure for this data set?

2, 2, 0, 5,1, 4,1, 3, 0, 0, 1, 4, 4, 0,1, 4, 3, 4, 2, 1 Mean- (2+2+0+5+1+4+1+3+0+0+1+4+4+0+1+4+3+4+2+1)/20= 2.15 Median- 2.10 Mode- numbers 1 and 4 The most appropriate measure for this data set would be mean as it involves all the numbers combined.

2. Based on the scale of measurement for each variable listed below, which measure of central tendency is most appropriate for describing the data?

a. The time…show more content…

c. Note the ways 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. Means are about the same, while the range is twice as wide for CEO’s indicating some CEOs have much larger desks and some have smaller desks.

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., freedom, choice) and half were neutral (e.g., whisper, hammer). The key focus of the study was on how long it took people to press the button *(“response latency”) for each kind of real word, averaged over the many words of each type. The table below
