Arranging the given data in ascending order:
0, 8, 9, 11, 11, 17, 18, 20, 24, 25, 25, 25, 29, 30, 30, 44, 50
Here, n = number of terms = 17
∴ Median
=th term
= = 9th term = 24
and, Mode = 25 (maximum three time)
and, Range = (Highest score – Lowest score)
= 50 – 0 = 50
Mean of the median, mode and range for the data
= = ==33.
