University of Phoenix Material Week 2 Practice Worksheet Prepare a written response to the following questions. 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? The mean would be the sum of all numbers which is 2+2+0+ 5+1+ 4+1+ 3+ 0+ 0+ 1+ 4+ 4+ 0+1+ 4+ 3+ 4+ 2+ 1=124. X(sum)/N=124/20. N=6.2. The median would be the middle score, the sum of all numbers added together (124) and divided by (20)=6.2. This would be the middle score. The mode is the value in a data set that occurs most often or most frequently. 0,0,0,0,1,1,1,1,1,2,2,2,3,3,4,4,4,4,5. We learn in our chapter reading that The mode would be 1.

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 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. 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)
