Question

Runs scored by Ravi in his last seven innings are given below :

$68,74,82,100,20,18,58$

Find the mean of runs scored by Ravi in an inning.

Answer 1

Finding the mean of the given data:

Given,

Runs scored by Ravi in his last seven innings are $68,74,82,100,20,18,58$

We know that,

$\mathrm{Mean}=\frac{\mathrm{Sum}\mathrm{of}\mathrm{all}\mathrm{observations}}{\mathrm{Total}\mathrm{number}\mathrm{of}\mathrm{observations}}$

$=\frac{68+74+82+100+20+18+58}{7}$

$=\frac{420}{7}$

$=60$

Hence, the mean of runs scored by Ravi in an inning is $60$ runs.
