Question

Find the mean of 9,11,8,20,10,16,12

Answer 1

Answer:

MEAN: sum of all time value / no of values

Answer 2

Answer:

The mean of the given data will be$\begin{aligned}\frac{86}{7}\end{aligned}$.

Step-by-step explanation:

Given: $9,11,8,20,10,16,12$

We have to find the mean of the above data.

• As we know that 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,

$9,11,8,20,10,16,12$

Here,

$\text { Sum of terms }=9+11+8+20+10+16+12=86\\\text { Number of terms }=7$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{86}{7}\end{aligned}$
