What is the difference between a class boundary and a class limit? (Select all that apply.) Class limits are possible data values. Class limits specify the span of data values that fall within a class. Class boundaries are values halfway between the upper class limit of one class and the lower class limit of the next. Class boundaries are possible data values. Class boundaries specify the span of data values that fall within a class. Class boundaries are not possible data values. Class limits are not possible data values. Class limits are values halfway between the upper class boundary of one class and the lower class boundary of the next.

Step 1

Class limits are possible data values: This is true. Class limits are the smallest and largest values that can be included in a class. They are actual data values that can be observed in the data set. Show more…

00:01 What is the difference between a class boundary and a class limit? well, before we go ahead and look at these, let me just talk a little bit about the two.

00:08 So if we have a frequency distribution, you can have classes.

00:12 And so i'm going to say we have a class maybe from, let's go two to ten, and then that would be like 11 to 19.

00:25 I'm sorry, my mind went blank for a second.

00:27 And then we would go, here would be 20 to 30 to 28.

00:32 28.

00:33 So there we would have our classes.

00:36 So that means our class limits are 210, 11, 19, 20, and 38.

00:42 Now the boundaries is the average value between the lower class limit and the upper class limit before it.

00:50 So that's going to be like 10 .5, 10 .5.

00:54 This would be 19 .5, 19 .5.

00:59 And if we continued, then that would end up being 28 .5 and this would end up being 1 .5.

01:06 So those are the differences there.

01:08 These are our boundaries and then these are our limits.

01:13 Okay, limits boundaries.

01:16 Now let's look at our questions.

01:18 Class limits are possible data values.

01:21 So that first one, that would be true because we're looking at anything between 2 and 10.

01:25 So if the first one be true, class limits specify the span of data values that fall within a class...
