Question

For the given data given below, calculate the mean of its median and range.
6, 2, 5, 4, 3, 4, 4, 2, 3

• A. 5
• B. 6
• C. 4
• D. 7

Answer 1

The correct option is C 4

Arranging the data in a ascending order, we get
2, 2, 3, 3, 4, 4, 4, 5, 6
Since, observations are odd in number.
∴ Median = Middle most observation
= 4
The range of the given data set
= 6 - 2
= 4
Now, the mean of median and range
= $\frac{4+4}{2}$
= $\frac{8}{2}$
= 4
