3. The stem-and-leaf display below shows the exam scores for a class of students. Stem-and-leaf of Scores N = 18 Leaf Unit = 1.0 1 1 1 2 6 6 1247 (6) 7 123469 6 8 2357 2 9 23 24 3 4 5 5 (a) Construct a boxplot for these scores. Do this by hand, show all workings as illustrated in class. You will get a slightly different boxplot from R, which is not acceptable for this question. (b) Excluding the outlier, what is the shape of the distribution for these scores? (c) Name an appropriate measure of location and an appropriate measure of variability for these data together with their values.
