When presented with a graph, what should you first identify?

• A. The color scheme used in the graph
• B. The independent and dependent variables
• C. The author's opinion on the data
• D. The number of data points plotted

Answer: (B)

Identifying the independent and dependent variables is crucial when presented with a graph because it helps you understand the relationship being depicted. The independent variable is typically plotted on the x-axis and represents the variable that is manipulated or controlled in an experiment, while the dependent variable is plotted on the y-axis and represents the outcome that is measured. By recognizing these variables first, you can better interpret the overall trends and patterns in the data, as well as understand how changes in the independent variable affect the dependent variable. This foundational step sets the stage for a comprehensive analysis of the graph and the underlying data it represents.
