Answer 1

MAD: Mean Absolute Deviation

The given Data are : 65, 52,43,51

`\text{Mean(m) = }(65+52+43+51)/(4)\text{ = }(211)/(4)\text{ = 52.75}`
`\begin{gathered} M.A.D=\frac{\sum ^{}_{}|x\text -m}{n} \\ \text{ =}(|65-52.75|+|52-52.75|+|43-52.75|+|51-52.75|)/(4) \\ =(12.25+0.75+9.75+1.75)/(4) \\ =(24.5)/(4) \\ =\text{ 6.125} \end{gathered}`
