The marks obtained by (out of 100 ) a group of students are given below:76,98,24,58,69,98,81,77,45,91Find the mean of the given data.

Given :

Marks obained by the students are 76,98,24,58,69,98,81,77,45,91.

To do :

We have to find the mean of the given marks.

Solution :

Number of observations $= 10$.

We know that,

$Mean = \frac{Sum of the observations of the given data}{Number of observations}$

            $= \frac{(76+98+24+58+69+98+81+77+45+91)}{10}$

            $= \frac{717}{10}$

            $= 71.7$

The mean of the given marks is 71.7.
