3.1 SOC A variety of information has been gathered from a sample of lower- and upper-year students living in residence at a large university, including their region of birth; the extent to which they support legalization of marijuana (measured on a scale on which 7 5 strong support, 4 5 neutral, and 1 5 strong opposition); the amount of money they spend each week out-of-pocket for food, drinks, and entertainment; how many movies they watched in their residence rooms last week, and their opinion of cafeteria food (10 5 excellent, 0 5 very bad). Some results are presented below. Find the most appropriate measure of central tendency for each variable for lower-year students and then for upper-year students. Report the measure you selected as well as its value for each variable (e.g.,

“Mode 5 3” or “Median 5 3.5”). (HINT: Determine the level of measurement for each variable first. In general, this will tell you which measure of central tendency is appropriate. See Section 3.5 to review the relationship between measure of central tendency and level of measurement. Also, remember that the mode is the most common score, and especially, remember to array scores from high to low before finding the median.)
