Consider the data set 2, 2, 3, 6, 10. (a) Compute the mode, median, and mean.
(b) Multiply each data value by 5. Compute the mode, median, and mean.
(c) Compare the results of parts (a) and (b). In general, how do you think the mode, median, and
mean are affected when each data value in a set is multiplied by the same constant?
(d) Suppose you have information about average heights of a random sample of airplane
passengers. The mode is 70 inches, the median is 68 inches, and the mean is 71 inches. To
convert the data into centimeters, multiply each data value by 2.54. What are the values of the
mode, median, and mean in centimeters?
