Answer 2

Answer:

The mean of the given data set will be 20.

Step-by-step explanation:

Given: $20,23,2,8,12,55$

We have to find the mean of the above data set.

• 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,

$20,23,2,8,12,55$

Here,

$\text { Sum of terms }=20+23+2+8+12+55=120\\\text { Number of terms }=6$

So, the mean of the above data set will be:

$\begin{array}{l}\text { Mean }=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean }=\frac{120}{6} \\\\\text { Mean }=20\end{array}$
