Let's solve this question.
00:01
In this question we have given the data that is 11, 50, 30 up to 44.
00:09
Now here we have given the 30 total data and we need to construct a frequency distributor with the number of class that is equals to 5.
00:23
So here we can say here it is class, here it is frequency f, then here we need to find the midpoint, then here we need to find the class boundary, then here it is relative frequency and here it is cumulative frequency.
00:52
So here the class for the given data that is 0 to 10, 11 to 21, then 22 to 32, 33 to 43 and 44 to 54.
01:08
So here it is total.
01:10
Here frequency that is 2, 7, 7, 7, 7.
01:14
So here the total frequency that is n is equals to 30.
01:19
Now here the midpoint that is the lower point of last point or we can say the endpoints of class that is sum of the endpoints of the class divided by 2 that is 0 plus 10 divided by 2 that is 5, 11 plus 21 divided by 2 that is equals to 16 and so on...
