The simple frequency distribution below shows the scores from 40 people who were asked to rate on a scale from | to 7 their attitudes toward stem cell research (with I being the most favorable attitude toward stem cell research and 7 being the least favorable). Attitude toward Stem N+1 Cell Research fx Position of the Man = 2 56 Position of Median = 40 + 1 = 41 = 20.5 Mode - 7 8 40 2 2 32 30 7 27 35 - Median = 2 4 + 5 = 4.5 20 24 2 NWAVIA 14 12 X =LA 10 6 N 7 N = 40 170 Mean = 170 = 4.25 40 Find (a) the mode, (b) the median, and (c) the mean. What must you assume about the scale for the mean to be meaningful? Must assume that the data is interval. That is, that there is approximately equal spacing between the response categories
