Which of the following can be determined based on the data above?

  • A. mean only
  • B. mean and median only
  • C. mean, median, and mode only
  • D. mean, median, mode, and range

Correct Answer: D

Explanation:

D

A stem-and-leaf plot shows the tens digit to the left of the vertical line and the units digits to the right of the vertical line. Thus, in the second row, the first number is 11, and the next is 14. Because all of the numbers of the data set are given, all statistical measures (mean, median, mode, and range) can be assessed.
