question 24 of 25
for which purpose would you most likely use a bar graph?

a. to show how many people in one city prefer paper bags and how many prefer plastic bags

b. to show what percentage of people in one city prefer paper bags to plastic bags

c. to show how many paper and plastic bags are used by the people of one city over several years

d. to show the relationship between paper or plastic bag preference and a person’s city

Explanation:

A bar graph is best for comparing discrete categories (like two groups: paper bag preferrers and plastic bag preferrers) and showing their quantities. Option A involves comparing two categories (paper vs. plastic bag preferences) with counts. Option B is about percentages, better for a pie chart. Option C involves change over time, better for a line graph. Option D involves a relationship between two variables, better for a scatter plot or other relationship - showing graphs.

Answer:

A. To show how many people in one city prefer paper bags and how many prefer plastic bags
