According to the Question,
- Given That, the frequency distribution of the score of 40 learners.
Class interval frequency
56-63 1
48-55 10
40-47 12
32-39 6
24-31 3
16-23 8

2) For Median, If there are two number in the middle then you need to find their mean. 1 3 6 8 10 12 middle numbers are 6 and 8.
Median = (6+8) / 2 = 7
3) Mode = 3 × Median - 2 × Mean
Mode = 3×7 - 2×6.66
Mode = 7.68
