In the context of scatterplots, how many variables are typically displayed on a standard scatterplot?

• A. $4$ variables
• B. $1$ variable
• C. $3$ variables
• D. $2$ variables

Answer: (D)

Verified step by step guidance

1. Understand that a scatterplot is a graphical representation used to display the relationship between two quantitative variables.
2. Recall that each point on a scatterplot corresponds to one observation with coordinates determined by two variables: one plotted on the x-axis and the other on the y-axis.
3. Recognize that while additional variables can be represented using colors, sizes, or shapes of points, the standard scatterplot fundamentally displays only two variables.
4. Therefore, identify that the typical scatterplot shows exactly two variables, one on each axis, to visualize their relationship.
5. Conclude that the correct answer to how many variables are typically displayed on a standard scatterplot is two variables.
