From the data set given, the smallest value is equal to 157 and the largest value is 201.
00:14
So, first we can find the range of the data set which is obtained by the largest value minus smallest value.
00:22
So, 201 minus 157 is equal to 44 is the range of the value.
00:28
Now, let us consider the class.
00:31
It is not mentioned the class width.
00:33
We have to just make a frequency distribution table.
00:35
So, let us consider a suitable class width as explained here.
00:41
So, the number of classes will be number of classes here desired will be equal to range divided by the class width.
00:54
So, this is equal to 44 divided by 10.
00:59
So, which is equal to 4 .4 which means that this can be approximated to 5.
01:05
So, the five classes are the same...
