Given the following data: (a) Draw a boxplot. (b) Calculate the standard deviation of these data and divide every score by the standard deviation. (c) Draw a boxplot for the data in (b). (d) Compare the two boxplots. Compare the mean, standard deviation, and variance for the data in Exercise 5.1 with their trimmed and Winsorized counterparts. The data in Exercise 5.1 Given the data you created in Exercise 5.6, show that multiplying or dividing by a constant multiplies or divides the standard deviation by that constant.
