Profit per shop less than (%)102030405060No. of shops1230577794100
Profit per shop less than (%)102030405060No. of shops1230577794100
Answer: Option A
:
A
Firstly, the cumulative frequency (CF) table is drawn.
C.ICFFrequency0−10121210−20301820−30572730−40772040−50941750−601006Total100
n2=1002=50
C.F nearest to 50 and greater than 50 is 57.
∴Median=l+(n2−cff)×h
Where l is lower class limit of median class.
n is total number of observations.
cf is the cumulative frequency of the class preceding the median class.
f is the frequency of the median class and h is the class size.
Median=20+(50−3027)×10
Median = 27.4
