Mathematics Question on Mode of Grouped Data
The given distribution shows the number of runs scored by some top batsmen of the world in one-day international cricket matches.
| Runs scored | Number of batsmen |
|---|---|
| 3000 - 4000 | 4 |
| 4000 - 5000 | 18 |
| 5000 - 6000 | 9 |
| 6000 - 7000 | 7 |
| 7000 - 8000 | 6 |
| 8000 - 9000 | 3 |
| 9000 - 10000 | 1 |
| 10000 - 11000 | 1 |
Find the mode of the data.
Answer
From the data given above, it can be observed that the maximum class frequency is 18, belonging to class interval 4000−5000.
Therefore, modal class = 4000−5000
Lower limit (l) of modal class = 4000
Frequency (f1) of modal class = 18
Frequency (f0) of class preceding the modal class = 4
Frequency (f2) of class succeeding the modal class = 9
Class size (h) = 1000
Mode = l + (2f1−f0−f2)f1−f0×h
Mode = 4000+(2(18)−4−918−4)×1000
Mode =4000+[2314000]
Mode = 4000 + 608.695
Mode = 4608.695
Therefore, mode of the given data is 4608.7 runs.
