in working with two variables related by a regression equation, the in a variable is the amount that it changes when the other variable changes by exactly one unit.
options: residual, probability, response, marginal change

Explanation:

To solve this, we analyze each option:

• Residual: The difference between observed and predicted values, not related to change per unit.
• Probability: Measures likelihood, not about variable change.
• Response: The dependent variable's value, not the change.
• Marginal change: Defined as the change in a variable when another changes by one unit, matching the description.

Answer:

marginal change
