Answer
Here, maximum = 43.2 and minimum = 23.6.
Range = 43.2 - 23.6 = 19.6
Let us form 5 classes of each size 4.
Since, we want to score 43.2 in last class and 43.5 is the upper limit of the last class, so the lower limit of first class is 23.5
The frequency distribution table of the given data is as follows :
| Classes | Tally marks | Frequency |
|---|---|---|
| 23.5 - 27.5 | IIII | 4 |
| 27.5 - 31.5 | 7 | |
| 31.5 - 35.5 | IIII | 4 |
| 35.5 - 39.5 | IIII | 4 |
| 39.5 - 43.5 | 11 |
