Question

find the mean of 2,5,9,5,7,3
​

Answer 1

Answer:

$mean = \frac{sum \: of \: all \: observation}{no \: of \: observaion} \\ = \frac{2 + 5 + 9 + 5 + 7 + 3}{6} \\ = \frac{31}{6} \\ = 5.166$

Answer 2

Answer:

The mean of the given data will be$\frac{31}{6}$.

Step-by-step explanation:

Given: $2,5,9,5,7,3$

We have to find the mean of the above data.

• As we know, the mean of a data set is the sum of the terms divided by the total number of terms.
• The formula for mean is:

        $\text { Mean }=\frac{\text { Sum of terms }}{\text { Number of terms }}$

We are solving in the following way:

We have,

The given data set is$2,5,9,5,7,3$.

Here,

$\text { Sum\ of terms }=2+5+9+5+7+3=31\\\text { Number of terms }=6$

So, the mean of the above data will be:

$\begin{array}{l}\text { Mean }=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean }=\frac{31}{6}\end{array}$
