Question

The median of the following data is:

31, 37, 43, 42, 25, 46, 45, 39, 32

1. 25
2. 42
3. 46
4. 39

Answer 1

Correct Answer - Option 4 : 39

Concept:

The median is the middle number in a data set when the numbers are listed in either ascending or descending order.

If total number of observation (n) is odd then, Median = (n + 1)^th/2 observation

Calculation:

Given data is-

31, 37, 43, 42, 25, 46, 45, 39, 32

Now, the given data is in ascending order- 25, 31, 32, 37, 39, 42, 43, 45, 46

The median of this data is the middlemost number of this data (as the total number of data is odd)

= [(9 + 1)/2]th = [10/2]th = 5th number

So, the required median is 39.
