Question

Find the mean of the data: $10.25,9,4.75,8,2.65,12,2.35$

Answer 1

Given data is,

$10.25,9,4.75,8,2.65,12,2.35$

$\Rightarrow$ Number of observations $\left(n\right)=7$.

Since, Mean $\left(\overline{x}\right)=\frac{\sum x}{n}$

$\Rightarrow$ Mean $=\frac{\text{Sum of all the observations}}{\text{Number of observations}}$

$\Rightarrow \overline{x}=\frac{10.25+9+4.75+8+2.65+12+2.35}{7}$

$\Rightarrow \overline{x}=\frac{49}{7}$

$\Rightarrow \overline{x}=7$

Therefore, the required mean of the data is$7$.
