What term best describes a graph with a vertical axis, a horizontal axis, and data points?

• A. Line chart
• B. Histogram
• C. Scatter plot
• D. Bar graph

Answer: (C)

A scatter plot uses a vertical axis and a horizontal axis to plot individual data points, showing the relationship between two quantitative variables. Each point represents one observation with its two values, so you can quickly see patterns, such as whether the variables tend to increase together, decrease together, or show no clear relationship. It also helps identify clusters and outliers and can reveal whether the relationship is linear or more complex. This is different from a line chart, which connects points with lines to emphasize a trend over time or order rather than the direct relationship between two variables. A histogram focuses on the distribution of a single variable, using bars to show frequency in value bins. A bar graph compares different categories, with bars representing categorical data rather than pairs of numerical measurements.
