Question

Find mean of 1,2,3,4,5​

Answer 1

Answer:

$mean = \frac{1 + 2 + 3 + 4 + 5}{5} \\ \\ \\ = \frac{15}{5} \\ \\ \\ \\ = 3$

Answer 2

Answer:

The mean of the given data will be 3.

Step-by-step explanation:

The given data is 1,2,3,4,5​.

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 data is 1,2,3,4,5​.

Here,

$\text { Sum of terms }=1+2+3+4+5=15\\\text { Number of terms }=5$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{15}{5} \\\\\text { Mean } &=3\end{aligned}$
