Calculate the mean deviation of the following income groups of five and seven members from their medians: 1st income group (in Rs.): 4000 4200 4400 4600 4800 2nd income group (in Rs.): 3800 4000 4200 4400 4600 4800 5800

Explanation

For first data,


Since the data is arranged in ascending order `4000, 4200, 4400, 4600, 4800`

Median = `4400`

We know that,

`M.D=1/n sum_(i=1)^n(d_i)`

`((x),(4000),(4200),(4400),(4600),(4800),(Total)),((x_i-4400),(400),(200),(0),(200),(400),(1200))`

`M.D=1/5(1200)`
