Answer 2

Given: $13,16,12,14,19,12,14,13,14$

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,

$13,16,12,14,19,12,14,13,14$

Here,

$\text { Sumof terms }=13+16+12+14+19+12+14+13+14=127\\\text { Number of terms }=9$

Now, the mean of the given data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\text { Mean } &=\frac{127}{9}\end{aligned}$

Hence, we get

$\begin{aligned}\text { Mean } &=\frac{127}{9}\end{aligned}$
