Which graph is used to show the relationship between two sets of data?

• A. Bar Graph
• B. Line Graph
• C. Pie Chart
• D. Scatter Plot

Answer: (D)

A scatter plot is used to show how two variables relate to each other. By plotting pairs of data as points on a grid (one variable on the horizontal axis and the other on the vertical axis), you can see patterns as one variable changes with the other. If the points tend to rise together, there’s a positive relationship; if one tends to rise while the other falls, there’s a negative relationship; if the points don’t show any clear pattern, there may be little to no relationship. Bar graphs compare different categories of a single variable; line graphs show trends over time or another continuous measure by connecting data points; pie charts display parts of a whole. Therefore, when you want to understand how two data sets relate, a scatter plot is the best choice.
