Data Handling

Question

Wired Faculty App

A cricketer scores the following runs in eight innings:
58, 76, 40, 35, 46, 45, 0, 100
Find the mean score.

Solution

Runs scored by the cricketer are 58, 76, 40, 35, 46, 45, 0, and 100.

$Mean score = \frac{Total runs scored in all the innings}{Total number of the innings}$

Mean score = $\frac{58 + 76 + 40 + 35 + 46 + 45 + 0 + 100}{8} = \frac{400}{8} = 50$

Therefore, mean score is 50.
