A student in an intro stats course collects data at her university. She wants to model the relationship between student jobs and GPA. She collects a random sample of students and asks each for their GPA and whether or not they have a job. If she wanted to make a scatterplot and find a linear model, which condition has she violated?

A. Outlier Condition

B. Straight Enough Condition

C. Quantitative Variables Condition

D. No conditions have been violated; she should proceed with her model.

Solution

C. Quantitative variables condition

Too make a linear model for a scatter plot, both variables have to be quantitative. However, here, the variable \"whether or not they have a job\" is categorical, not quantitative.
