Show answer & explanation
Correct answer: C
Concept
A frequency distribution lists values or classes together with the number of observations in each.
For grouped continuous data, a histogram uses adjoining rectangles across class intervals. With equal class widths, height represents frequency; with unequal widths, height represents frequency density, so rectangle area represents frequency.
Application
The stem specifies grouped continuous data and adjoining class intervals, which describes a histogram.
Contrast
A bar chart uses separated bars for discrete categories.
A line chart connects ordered data points, commonly to show change over time.
A pie chart divides a whole into proportional sectors.
Therefore, the required graphical representation is a histogram.
