Find out mean deviation and coefficient of mean deviation, using arithmetic mean from the following data:

Explanation

`barX=(sumfm)/(sumf)=(2,375)/(75)31.66`
Mean Deviation from Arithmetic Mean
`MD_(barX)=(sumf|dX|)/(sumf)=(800.10)/(75)=10.67`
Coefficient of Mean Deviation
`=(MD_(barX))/(X)=(10.67)/(31.67)=0.34`
Mean Deviation =10.67, Coefficient of Mean Deviation =0.34.
