Answer» So, now lets arrange all the numbers in ASCENDING order 7, 8, 9, 10, 12, 13, 15, 15, 15, 20, 20, 20, 20, 25, 25 Mean = 7 + 8 + 9 + 10 + 12 + 13 + 15 + 15 + 15 + 20 + 20 + 20 + 20 + 25 + 25 = 234/15 = 15 9/15 = 15.6 Median = N+1 / 2 where n is NUMBER of terms = 15 + 1 / 2 = 16/2 = 8th term = 15 Mode = 20 as it is repeated most number of times.
