Below are sample questions representative of the exercises included on this worksheet and related ALG2.222 Recognizing Nonlinear Patterns in Residuals skill assessments:

Problem 1Difficulty: Mastery

A residual plot for a linear model shows both a curved center pattern and a wider spread at high x-values. Which conclusion is most complete?

AThe line may be missing nonlinear structure, and the prediction variability may also change across x.

BThe line is definitely perfect because two issues balance each other.

CThe wider spread proves the curve is not important.

DThe residual plot should be replaced by the original scatterplot only.

Solution & Explanation:The curved pattern suggests a nonlinear mean relationship, and the wider spread suggests changing variability. Both issues should be considered.

Problem 2Difficulty: Mastery

A linear model's residual plot is shown. There are about as many positive as negative residuals, but the points follow a smooth arch. Which conclusion is best?

AThe residual plot proves that every prediction is exact.

BThe balanced signs do not make the residuals random; the arch suggests a nonlinear model.

CThe balanced signs prove the line is appropriate.

DThe arch should be ignored because only the number of positive residuals matters.

Solution & Explanation:Having equal numbers of positive and negative residuals is not enough. The smooth arch is a systematic nonlinear pattern.

Problem 3Difficulty: Mastery

Why can plotting only absolute residuals make it harder to detect nonlinear patterns?

AIt changes every nonlinear model into a linear model.

BIt prevents residuals from being compared to predicted values.

CIt hides whether residuals are positive or negative, so curves based on sign can disappear.

DIt makes every residual equal to zero.

Solution & Explanation:Signs matter. A U-shape or arch often depends on positive and negative residuals appearing in order, which absolute values can hide.
