Question

29. Calculate mean deviation about median for the following data:
Class
0-10 10-20 20-30 30-40 40-50 50-60
Frequency
6 7
15 16
16 4 2 .​

Answer 1

Answer:

first find commutative frequency

6

6+7=13

13+15=28

28+16=44

44+16=70we take this as cf because 102is total frequency =102/2=51

70+42=112

Step-by-step explanation:

formula for finding median:-

L+(n/2-cf)/f×h

40+(102/2-44)/16×10

40+(51-44)/16×10

40+(7/6)×10

40+(70/16)

640+70/16

710/16
