Final answer:
The instructor's study is an example of linear regression, seeking to predict final course scores based on placement test scores.
Step-by-step explanation:
The instructor's study of the relationship between students' placement test scores and final course scores is an example of linear regression. In a linear regression, the intent is to find a linear relationship between two variables, in this case, the placement scores (independent variable) and the final course scores (dependent variable).
The instructor would use linear regression analysis to create a model that can predict final course scores based on placement test scores.
