In a chart or graph, what does the x-axis typically represent?

• A. The dependent variable or the outcome being measured
• B. The independent variable or the variable that is manipulated
• C. The total population size involved in the study
• D. The average result of the experiment

Answer: (B)

The x-axis in a chart or graph typically represents the independent variable, which is the variable that is manipulated or changed in an experiment. This is the factor that researchers control to observe how it influences the dependent variable, often plotted on the y-axis. By showing the independent variable on the x-axis, the graph allows for easier visualization of any trends or relationships with the dependent outcome. This standard convention helps ensure clarity in data representation and enables viewers to understand the cause-and-effect dynamics being studied.
