The median is 15.
(0, 2, 15, 16, 17) 0+2+15+16+17 = 50 50/5 = 10 The median is 15, the mean is 10.
14. Put in order: {1, 6, 10, 12, 12, 13, 15, 19, 27, 31, 32, 40} There are 12 data items, so the median is the (12 + 1) ÷ 2 = 61/2th data item. As 61/2 is not a whole number, take the mean average of the 6th and 7th data items: 6th is 13, 7th is 15 ⇒ median = (13 + 15) ÷ 2 = 14
Mean = 7.9 Median = 7 and 8 Mode = 4 and 12 Range = 2 to 15.
The answer is 8.5
