Question

If a certain set of observations has a mean of 22.5 and a median of 20, then what will be the mode of that set of observations?
1. 12
2. 14
3. 16
4. None of the above

Answer 1

Correct Answer - Option 4 : None of the above

Given:

Mean of set of observations = 22.5

Median of set of observations = 20

Formula used:

Mode = 3 Median - 2 Mean

Calculations:

Mode = 3 × 20 - 2 × 22.5

⇒ 60 - 45 = 15

 The mode of certain set of observations is 15
