Question

Determine whether the statement is true or false. If it is false, rewrite it as a true statement.

Class boundaries ensure that consecutive bars of a histogram touch.

Accepted Answer

Hi everyone, let's take a look at this practice problem. This problem says class boundaries are used to ensure that adjacent bars and histogram do not touch. Decide whether the preceding statement is true or false. If it is false, rewrite it correctly. And we're going 4 possible choices as our answers. For choice A, we have false. Class boundaries create gaps between. Consecutive bars in a histogram. For choice B, we have true. Class boundaries prevent adjacent bars in a histogram from overlapping. For Choice C, we have false class boundaries are used to ensure that adjacent bars in a histogram touch. And for choice D, we have false class boundaries cause adjacent bars and a histogram to overlap. So we need to decide whether our given statement here is true or false, and since our statement here is doing dealing with class boundaries, let's review some properties of class boundaries. So recall that class boundaries are values that eliminate gaps between adjacent classes in a histogram. They ensure continuous data representation by using precise decimal points, which means that histogram bars should touch to reflect continuous data. And so if we look at our statement here, it says that class boundaries are used to ensure that adjacent bars in a histogram do not touch. So this directly contradicts what we just said about the class boundaries causing the histogram bars to touch. That means that this statement is false. So that is the answer that we're looking for for this problem. Now, we need to rewrite this statement to make it true. So we could rewrite it as class batteries are used to ensure that adjacent bars in a histogram touch. And if we use that as our rewritten statement, and we look at our answer choices, we see that the correct answer choice corresponds to answer choice C, which says false class boundaries are used to ensure that adjacent bars in a histogram touch. So I hope that this explanation has been useful, and I'll see you in the next video.
