Answer 2

Answer:

The mean of the given data will be 4.

Step-by-step explanation:

Given: $1, 2, 3, 4, 5, 6, 7$

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 is$1, 2, 3, 4, 5, 6, 7$.

Here,

$\text { Sum of terms }=1+2+3+4+5+6+7=28\\\text { Number of terms }=7$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\text { Mean } &=\frac{28}{7} \\\text { Mean } &=4\end{aligned}$
