Should scatterplot markers be connected by a line?

Should scatterplot markers be connected by a line?

• A. True
• B. False
• C. It depends on the data
• D. Only if it's a time series

Answer: (B)

In the context of using scatterplots, connecting the markers with a line is not typically appropriate because scatterplots are used to display the relationship between two variables as individual data points. Each point represents a unique observation, showing how one variable is related to another. The purpose of a scatterplot is to visualize the distribution and correlation of the data, rather than to imply a specific trend or continuous relationship. When the markers are connected by a line, it can mislead the interpretation, suggesting a relationship that may not exist among the individual data points. Every scatterplot relies on the independence of points, allowing for a clear and honest representation of the observed data. Therefore, it is accurate to state that scatterplot markers should not be connected by a line, justifying the choice that indicates it is false.
