The variance of the residuals is constant Multiple linear regression assumes that the amount of error in the residuals is similar at each point of the linear model. Does the dependent variable need to be a continuous variable? A predictor variable is similar to an independent variable because they both are used to determine a relationship, typically to that of a dependent variable. c. 3x3 FTCE School Psychologist PK-12 (036) Prep, Human Growth and Development: Help and Review, Social Psychology: Homework Help Resource, Introduction to Educational Psychology: Certificate Program, Educational Psychology: Tutoring Solution, Research Methods in Psychology: Homework Help Resource, UExcel Abnormal Psychology: Study Guide & Test Prep, Abnormal Psychology: Homework Help Resource, Life Span Developmental Psychology: Homework Help Resource, Research Methods in Psychology for Teachers: Professional Development, Glencoe Understanding Psychology: Online Textbook Help, Create an account to start this course today.
