Question

find the mean deviation about the median for the following data4,6,9,3,10,13,2.​

Answer 1

Step-by-step explanation:

Arrange data in ascending order,

2,3,4,6,9,10,13

No. of observation n=7(odd)

Median =

2

n+1

=4

th

observation

Hence median =6

Now we calculate mean deviation about median, i.e;

⟹

7

∑∣x

i

−M∣

=

7

∣2−6∣+∣3−6∣+∣4−6∣+∣6−6∣+∣9−6∣+∣10−6∣+∣13−6∣

=

7

23

=3.28
