Question

Find the means of the data10.25,9,4,75,8,2.65,12,2.35

Answer 1

sum of observations is 123.25

no of observations is 8

123.25/8=15.406

Answer 2

Answer:

The mean of the given data will be$\frac{493}{32}$.

Step-by-step explanation:

Given: $10.25,9,4,75,8,2.65,12,2.35$

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 is used to calculate the mean is:

       $\text { Mean }=\frac{\text { Sum of terms }}{\text { Number of terms }}$

We are solving in the following way:

We have,

$10.25,9,4,75,8,2.65,12,2.35$

Here,

$\text { Sum of terms }=10.25+9+4+75+8+2.65+12+2.35=123.25\\\text { Number of terms }=8$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{123.25}{8} \\\\\text { Mean } &=\frac{493}{32}\end{aligned}$
