Final answer:
Scatterplots are not meant for categorical data; they are ideal for showing relationships between two quantitative variables, whereas bar graphs or pie charts are better for categorical data.
Step-by-step explanation:
The statement "A scatterplot is a great choice for displaying categorical data" is false. Scatterplots are better suited for displaying the relationship between two quantitative variables, where each point in the scatterplot represents the values of two variables for a single observation. For categorical data, which involves discrete categories or groups, a bar graph or a pie chart would be a more appropriate choice. Scatterplots are particularly useful to explore the potential correlation between variables, which can also be investigated using linear regression if the pattern of the data suggests a linear relationship.
