Consider the following frequency distribution:

- D9
Explanation
Total frequency N = 42, so the median is the average of the 21st and 22nd ordered values. Cumulative frequencies: 4s up to 6, 5s up to 10, 6s up to 15, 7s up to 19, 8s up to 25. Both the 21st and 22nd values are 8, so the median is 8.
