Marks: +1, -0

The mean deviation about the mean of the following data is nearly

Size(x)	1	3	5	7	9	11	13	15
Frequency(f)	3	3	4	14	7	4	3	4

Size (x)	Frequency (f)	x⋅f	\|x−x\|	f\|x−x\|
1	3	3	7	21
3	3	9	5	15
5	4	20	3	12
7	14	98	1	14
9	7	63	1	7
11	4	44	3	12
13	3	39	5	15
15	4	60	7	28
	N=Σf =42	Σxf =336	Σ(x−x) =40	Σf\|x−x\| =124
