Please help me to find the mean deviation from median........?

Question

Answer 1

Class interval
2 - 8	5	5	5	- 21.8	21.8
12 - 16	15	8	13	- 11.8	11.8
22 - 28	25	15	28	- 1.8	1.8
32 - 38	35	16	44	8.2	8.2
42 - 48	45	6	50	18.2	18.2
	50				61.8

 

Answer 2

Continuous....

The median group is " 22 - 28 " .

We need to estimate a single median value use the formula.

Where L is lower class boundary of the group containing the median.

N is the total number of data.

  is cumulative frequency of the groups before the median group.

is the frequency of the median group.

is the group width.

The formula to calculate mean deviation from median

= 61.8/50

= 1.236

Mean deviation from median = 1.236.
