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 b and dependent variable c can be analyzed using a scatterplot. only the relationship between independent variable a 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 pairs of variables (A - C and B - C), we need two separate scatter - plots. One scatter - plot for the relationship between A and C, and another for the relationship between B and C.

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.
