Hello students, here the data is 10, 15, 18, 22, 24, 27, 30, 32, 36, 40.
00:15
For my example, i took this data.
00:20
So, first we ask you to find the class limits.
00:27
So, class limits are the minimum and maximum values of each interval.
00:41
So, to find them, arrange the data in the increasing order first.
00:45
It's already in the increasing order only.
00:51
Then class limits for each interval are, so let's, let me take the class interval as 10 to 19, 19, 20 to 29 and then 30 to 39, 40 to 49.
01:20
So, here the lower limit is equal to 10 and the upper limit is equal to 19.
01:31
Similarly, here lower limit is equal to 20 and upper limit is equal to 29.
01:40
So, here this is lower limit, this is upper limit, then lower limit, upper limit.
01:46
So, then class boundaries.
01:48
The next question is about class boundaries.
02:00
So, the class boundaries are the midpoints between upper limit of one class and the lower limit of next class.
02:09
They help to create gapless and continuous scale, the class boundaries for each class.
02:17
So, the class boundaries 9 .5 to 19 .5, then 19 .5 to 29 .5, then 29 .5 to 39 .5, then 39 .5 to 40 .5...
