| X | 8 | 10 | 12 | 16 | 18 | 20 | 24 |
| F | 2 | 1 | 4 | 3 | 3 | 1 | 6 |
From the table, Calculate the median___________
- 24.0
- 17.0
- 18
-
16
The correct answer is: D
Explanation
When a group data is involved, cumulative frequency is used. The formula will be:
Median=[(N+1)/2]th
For member of odd number items. That is, where N is odd
Median=([N/2[N/2+1]th)/2
For member of odd number items. That is, where N is odd
Solution:
| X | 8 | 10 | 12 | 16 | 18 | 20 | 24 |
| F | 2 | 1 | 4 | 3 | 3 | 1 | 6 |
| Cumulative Frequency | 2 | 3 | 7 | 10 | 13 | 14 | 20 |
