Which of the following is not a standard component of a graph showing a dependent variable?

• A. A random decorative image
• B. Data points
• C. Axis labels
• D. A title describing the relationship

Answer: (A)

When presenting data about a dependent variable, a graph should clearly communicate what was measured and how it relates to the conditions you tested. The essential pieces are data points, axis labels, and a descriptive title.

Data points show the actual measurements of the dependent variable for each level of the independent variable, letting you see trends, patterns, or correlations. Axis labels indicate what each axis represents and include units, so you know what the numbers mean and how the variables relate. A title provides a quick description of the relationship being shown, giving viewers immediate context about which variables are involved and what the graph is illustrating.

A random decorative image doesn’t convey any data or meaning about the relationship, and it can distract from interpreting the graph, so it isn’t considered a standard component.
