Card 1 of 23

Why is a telephone number categorical despite containing digits?

A

15×2=3015 \times 2=3015×2=30.

B

Use a histogram for grouped continuous data and a stem-and-leaf diagram for manageable ungrouped numerical data.

C

A pie chart emphasises proportions of a whole, while a bar chart makes category frequencies easier to compare accurately.

D

It is a label, so numerical calculations are meaningless.
