A) histogram
B) frequency polygon
C) stem and leaf graph
D) all of the above are actually effective and equally useful for this data

Quizplus · Accepted Answer

A stem and leaf graph is least effective for this data because the data is categorical (number of meals skipped) and does not lend itself well to the format of a stem and leaf plot, which is better suited for continuous numerical data. Histograms and frequency polygons are more appropriate for displaying the distribution of this type of discrete numerical data.
