Question

find the median for the following frequency distribution: class interval;0_10,10_20,20_30,30_40,40_50,50_55,55and more. Frequency:5,8,18,23,27,12,7 iska answer h 38.26 h described this question and solution​

Answer 1

Answer:

Class Frequency Cumulative Frequency

0-10 12 12

10-20 13 25

20-30 25 50

30-40 20 60

40-50 10 70

Now 2N=35. Hence cumulative frequency just greater

than 35 is 50. The corresponding class is 20−30.
