Texts or calls? Refer to Exercise 91. A boxplot of the difference (texts – calls) in the number of texts and calls for each student is shown below.

(a) Do these data support the claim in the article about texting versus calling? Justify your answer with appropriate evidence.

(b) Can we draw any conclusion about the preferences of all students in the school based on the data from Mr. Williams’s statistics class? Why or

why not?

Given:

A boxplot is a frequent data analysis graph.

We may conclude from the box-plot showing the difference in the number of texts and calls for each student that the article's assertion about texting versus phoning is unsupported because the minimum value of the difference is negative, implying that these people call more than they text. There is also a trend to text more than call, although it is not as serious as the study claims. Only a few people text more than they call.

It is impossible to draw a conclusion regarding the preferences of all students because many students prefer to call over text, but many students prefer to text over call. As a result, the data yields mixed outcomes. There is a trend among students to text rather than phone, but this trend is not as strong as the data suggests, with a few outliers.
