Question

HELP PLEASE

A teacher was interested in the cafeteria food that students preferred in a particular school. She gathered data from a random sample of 200 students in the school and wanted to create an appropriate graphical representation for the data.

Which graphical representation would be best for her data?

Stem-and-leaf plot
Line plot
Histogram
Box plot

Answer 1

(c) Histogram

Explanation:

You want the sort of graphical representation that would be best for students' food preferences.

Categorical data

While the numbers of students will be numeric data, the preferred food will be non-numeric data. The best representation for non-numeric data will be a histogram.

Additional comment

A stem-and-leaf plot and some types of line plot also look somewhat like a histogram. The stems and leaves are generally numeric, but you could have something like ...

energy | x x x x

cola | x x x x x x x

water | x x

Of the choices here, it seems that "histogram" best covers the kind of graphic that is needed. A circle graph or radar chart may also work for the purpose.
