The correct answer is: C. The y-axis
The y-axis is the vertical axis of a chart. It is used to represent the dependent variable, which is the variable that is being measured or analyzed. The values entered in a data sheet are typically the dependent variable, so they are displayed on the y-axis.
The title area is the topmost part of a chart. It contains the title of the chart, which describes what the chart is about.
The legend is a box that contains labels for the different colors or symbols used in a chart. It helps the reader to understand what each color or symbol represents.
The x-axis is the horizontal axis of a chart. It is used to represent the independent variable, which is the variable that is being controlled or manipulated. The values entered in a data sheet are typically not the independent variable, so they are not displayed on the x-axis.
