25.77 is the Median

Step-by-step explanation:

Class                   cf                   f                less than

14.5 - 19.5           162                30             30

19.5 - 24.5          132                36              66

24.5 - 29.5          96                59              125

29.5 - 34.5          37                 24              149

34.5 - 39.5           13                 5                154

39.5 - 44.5           8                   2              156

44.5 - 49.5           6                  2                158

49.5 - 54.5           4                  0                158

54.5 - 59.5           4                  1                 159

59.5 - 64.5           3                   3              162

162/2 = 81  lies in 24.5 - 29.5

Median = 24.5  + 5 * (81 - 66)/59  = 24.5 + 1.27

= 25.77
