Question

Find the mean of:

vi. $5,2.4,6.2,8.9,4.1$ and $3.4$

Answer 1

Find the mean of $5,2.4,6.2,8.9,4.1$ and $3.4$

Number of data values $=6$

$\text{Mean}=\frac{\text{Sum of all data values or observations}}{\text{Number of data values or observations}}$

$\Rightarrow \text{Mean}=\frac{5+2.4+6.2+8.9+4.1+3.4}{6}$

$=\frac{30}{6}=5$

Hence, the mean of $5,2.4,6.2,8.9,4.1$ and $3.4$ is $5.$
