Question

Find the mean of the following data
40, 30, 20,0,60,10​

Answer 1

$Mean = \frac{sum \: of \: all \: observations}{total \: number \: of \: observations}$

So, the mean of the following data is

$= \frac{40 + 30 + 20 + 0 + 60 + 10}{6}$

$= \frac{ \cancel{160}}{ \cancel6}$

$= 26.66$

So, the mean of the following data is 26.66
