Question

what is the name of the type of data that a scatterplot is used to analyze?

univariate data
bivariate data
trivariate data
quadvariate data

Explanation:

Identify the variables in a scatterplot

A scatterplot graphs individual data points on a two-dimensional coordinate system with a horizontal axis (\(x\)-axis) and a vertical axis (\(y\)-axis). This means each plotted point represents a pair of numerical values corresponding to two distinct variables.

Define the data type based on variable count

• "Uni-" means one, so univariate data involves a single variable.
• "Bi-" means two, so bivariate data involves two variables.
• "Tri-" means three, so trivariate data involves three variables.
• "Quad-" means four, so quadvariate data involves four variables.

Since a scatterplot is used to analyze the relationship between exactly two variables, it is used to analyze bivariate data.

Answer:

• univariate data
• bivariate data (Correct answer)
• trivariate data
• quadvariate data
