Problem, we have been asked what we need to do in order to find the class boundaries.
00:04
Now, for that, consider an example.
00:06
Let us consider the classes 1, 2, 3, 4, 2, 6, 7, 29.
00:13
Now, the lower class limits are 1, 4, and 7, and the upper class limits are 3, 6, and 9.
00:20
Now, if we want to find the class boundaries, what we need is we need the upper class boundary of this class to be the same as the lower class boundary of the next class.
00:29
Similarly, the upper class boundary of this class will be the same as the lower class boundary of the next class.
00:34
How do we do that? we're going to subtract 0 .5 from each of the lower class limits, and we're going to add 0 .5 to each of the upper class limits.
00:43
So this is a lower class limit...
