Can plss any one answer this question
Q). Find the median of the following data by converting into a grouped frequency distribution.

Dear student
Class-Intervals No.of consumers Cumulative frequency
65-85 4 4
85-105 5 9
105-125 13 22
125-145 20 42
145-165 14 56
165-185 8 64
185-205 4 68

Here N=68N2=682=34Thus, the cumulative frequency just greater than 34 is 42 and the corresponding class is125-145Therefore,125-145 is the median class.Here, l=125,f=20,F=22 and h=20We know thatMedian=l+N2-Ff×hMedian=125+34-2220×20Median=125+12Median=137
