Question

class intervals-
0-5,
6-11,
12-17,
18-23,
24-29
frequency 13,10,15,8,11 find the upper limit of median class​

Answer 1

Answer:

Classes are not continuous, hence make them continuous by adding 0.5 to the upper limits and subtracting 0.5 from the lower limits.

C.I Frequency Cumulative Frequency

0−5.5 13 13

5.5−11.5 10 23

11.5−17.5 15 38

17.5−23.5 08 46

23.5−29.5 11 57

Total ∑f=57

Class interval can't be negative hence the first C.I. is starting from 0.

Now to find median we calculate

∑f

=

57

=28.5

∴ Median class 11.5−17.5

So, the upper limit is 17.5
