A student wants to use a curve to represent the number of students in each class over the school day. The student’s friend says a bar chart should be used. Who is correct, and why?

▸

The student; the curve is a more accurate representation.

▸

The friend; the data on class sizes are discrete but a curve implies the data are continuous.

▸

Both; either form of the graph gives the same information.

▸

Neither; the graph should present the cumulative frequency.
