Question

unit 4 test: graphs and describing distributions multiple choice
which types of graphs are best at representing quantitative data? please select all possible choices.
bar graph
box and whisker plot
stem and leaf plot
histogram
pictograph
pie chart
line graph

Explanation:

• Box and whisker plot: Shows distribution of quantitative data using quartiles.
• Stem and leaf plot: Displays quantitative data while retaining individual data points.
• Histogram: Represents frequency distribution of quantitative data in intervals.
• Line graph: Useful for showing trends in quantitative data over a continuous variable (e.g., time).

Bar graphs, pictographs, and pie charts are more commonly used for categorical data. Bar graphs can sometimes be used with quantitative data in a limited sense (e.g., comparing discrete quantitative values like number of items in different categories), but they are not as specialized for showing the full distribution and characteristics of quantitative data as the other four mentioned.

Answer:

box and whisker plot, stem and leaf plot, histogram, line graph
