Question

dependent variable c depends on both independent variable a and independent variable b. which statement is correct? the relationship between independent variable a and dependent variable c and the relationship between independent variable b and dependent variable c can both be analyzed using the same scatterplot. the relationship between independent variable a and dependent variable c, and the relationship between independent variable b and dependent variable c can both be analyzed, but they must be analyzed using separate scatterplots. only the relationship between independent variable a and dependent variable c can be analyzed using a scatterplot. only the relationship between independent variable b and dependent variable c can be analyzed using a scatterplot.

Explanation:

A scatter - plot is used to analyze the relationship between two variables. Since we have two different independent variables (A and B) and one dependent variable (C), we cannot analyze the relationship of A with C and B with C on the same scatter - plot. Each scatter - plot can only show the relationship between two variables. So, the relationship between \(A\) and \(C\) and the relationship between \(B\) and \(C\) must be analyzed using separate scatter - plots.

Answer:

The relationship between independent variable A and dependent variable C, and the relationship between independent variable B and dependent variable C can both be analyzed, but they must be analyzed using separate scatterplots.
