Question

which graph type would be best to compare the population sizes of different countries? a. pie chart b. scatter plot c. line graph d. bar graph

Explanation:

• Pie Chart: Shows parts of a whole. Not ideal for comparing population sizes of different countries as it focuses on proportions within a single entity.
• Scatter Plot: Used to show the relationship between two variables. Not relevant for comparing population sizes directly.
• Line Graph: Good for showing trends over time. Not the best for comparing discrete values (population sizes of different countries at a point in time).
• Bar Graph: Allows for easy visual comparison of discrete values (like population sizes of different countries). Each country can be a bar, and the height/ length of the bar represents the population size.

Answer:

d. Bar Graph
