Assignment #2 2.1 An instructor obtained the following set of scores from a 10-point quiz for a class of 26 students: 8, 5, 4, 5, 5, 7, 6, 4, 3, 4, 5, 6, 6, 4, 5, 5, 10, 6, 9, 5, 7, 8, 2, 6, 7, 4 a. b. Place the scores in a frequency distribution table. Sketch a histogram showing the distribution Using your graph, answer the following questions: 1. What is the shape of the distribution? 2. As a whole, how did the class do on the quiz? Were most scores high or low? Was the quiz easy or hard? 2.2 For each of the following situations, identify the measure of central tendency (mean, median, or mode) that would provide the best description of the "average" or most representative score.
