Question

kolantras math teacher plots student grades on their weekly quizzes against the number of hours they say they study on the night before. then draws the line of best fit. what does the slope of the line represent? answer: the change in expected quiz score for every additional one hour students spend on their homework. a prediction of a students quiz score if they spent 1 hour on their homework. the change in a students actual quiz score for every additional one hour that student spent on their homework. a students expected quiz score if they spent no time on their homework.

Explanation:

In a linear - regression context (line of best fit), the slope represents the change in the dependent variable (quiz score) for a one - unit change in the independent variable (hours spent on homework). It is an expected change based on the overall trend modeled by the line of best fit, not an actual score for a single student at a specific point.

Answer:

The change in expected quiz score for every additional one hour students spend on their homework.
