Question

Point of intersection of less than more than data of the ogive is (27,12) what is the total frequency

Answer 1

➡️Answer: Total frequency can be 23 or 24

➡️Solution:

Point of intersection of less than and more than data of the ogive is (27,12), gives the median data and it's frequency.

So, Median = 27

and it's frequency is 12.

Since Median is middle term of all the observations ,so total frequency might be 23 or 24.

Since for odd numbers we find that Median is (n+1)/2 th term
so, if n = 23

than only (n+1)/2 can be 12

or n = even, than n/2th, and n/2+1 th
