When would we want to use a pie chart?

• To show trends over time.

• To display the proportions of categories within a whole.

What is a key advantage of a bar graph over a pie graph, especially when comparing many data categories?

• Bar graphs are always more visually appealing.

• Bar graphs can represent cumulative data more effectively.

• Bar graphs make it easier to quickly compare the relative heights.

• Pie graphs cannot show percentages.

What is a primary distinction between a bar graph and a histogram?

• Bar graphs represent data over a range, while histograms represent specific data sets.

• Histograms represent data over a range, while bar graphs represent specific data sets.

• Bar graphs always show percentages, while histograms show raw frequencies.

• Histograms are used for qualitative data, bar graphs for quantitative data.

What is a defining characteristic of a relative frequency histogram?

• It only shows the highest frequency data.

• The total of all bars adds up to 100%.

• It is used for qualitative data only.

• It displays data as individual points.
