Correct Answer - Option 1 : 22.5
Formula Used:
Mean = Sum of all observation/Number of observation
Calculation:
Median:
Ascending order:
22 ,22, 22, 23, 23, 24, 24, 26, 29
⇒ The middle value is 23 so, the median is 23.
Mode:
| Observation |
Frequency |
| 22 |
3 |
| 23 |
2 |
| 24 |
2 |
| 26 |
1 |
| 29 |
1 |
| Total |
9 |
⇒ 22 is repeating maximum time so, the mode is 22.
Mean:
Mean = (Median + Mode)/2
⇒ Mean = (23 + 22)/2
⇒ Mean = 22.5
∴ The mean of median and mode is 22.5
The correct option is 1 i.e. 22.5
