What distinguishes multiple regression from simple regression?
Correct Answer
A) Multiple regression uses more than one predictor
Why this is correct: The original explanation states that multiple regression uses several independent variables (predictors) to estimate their simultaneous effect on the dependent variable (e.g., price). Simple regression uses only one predictor. Why the other choices are wrong: Multiple regression requires a larger sale price is false; price level doesn't define the model. Multiple regression is run more than once in turn describes a sequential process, not the defining characteristic. Multiple regression needs no dependent variable is incorrect; all regression models require a dependent variable. Exam tip: Simple regression: one predictor. Multiple regression: two or more predictors.

An appraiser includes both 'total room count' and 'bedroom count' as independent variables in a regression model estimating single-family home sale prices. The variance inflation factor (VIF) for 'bedroom count' is calculated as 12.3. What is the most appropriate appraisal action based on this result?
An appraiser runs a regression of sale price on GLA, age, and a binary variable for 'renovated' (1 = yes, 0 = no). The estimated coefficient for 'renovated' is $18,400 with a standard error of $6,200 and a t-statistic of 2.97.

To validate the functional form of a regression model used for adjustments, an appraiser plots residuals against predicted values and observes a clear inverted-U pattern. What does this pattern indicate, and what is the most defensible corrective action?
