What is a nonlinear relationship?

What is a nonlinear relationship?

• A. Changes in one variable do not match changes in another, often forming curves.
• B. Changes in one variable are always proportional to changes in another.
• C. The variables have a perfect linear relationship.
• D. The variables are independent.

Answer: (A)

Nonlinear relationships occur when the effect of one variable on another isn’t a constant proportion as values change. The rate of change varies, so the data curve or bends rather than following a straight line. That’s why the description of changes in one variable not matching changes in another, often forming curves, is the best fit. In compensation analytics, you might see this when costs or incentives rise at different rates after certain thresholds or when returns diminish or accelerate with scale. If changes were always proportional, you’d have a straight-line, linear relationship; if the variables were perfectly linear, the relationship would still be a straight line; if the variables were independent, there’d be no systematic relationship at all.
