Question

What is the mean absolute deviation for 7,5,1,6,2 and 3

Answer 1

Answer:

mean absolute deviation = 2

Step-by-step explanation:

Mean absolute deviation, M.A.D is given by

M.A.D= 1/n ∑ |Xi-X|

where i= 1 to n

X= mean of values

Xi= ith value

n=total number of values

Now\given values are 7,5,1,6,2 and 3

Mean= 7+5+6+1+2+3/6

  X= 4

Now

M.A.D= 1/6{(|7-4|+|5-4|+|1-4| +|6-4|+|2-4| +|3-4|}

        = 1/6 (12)

         =2 !
