    What are the requirements for a regression analysis?

    Predictors and a dependent variable on a scale.

    What is the minimum sample size for regression analysis?

    At least 10 participants per independent variable.

    What type of relationship is needed between variables in regression?

    A moderate correlation, ideally r of .3 or higher.

    How does simple regression differ from multiple regression?

    Simple regression uses one predictor; multiple uses several.

    What is a key condition for the variables in regression?

    They should be normally distributed and linearly related.

    What happens if variables are highly correlated in regression?

    It can distort the results and interpretations.

    What is hierarchical regression used for?

    To assess the impact of predictors in stages.

    What should guide the selection of regression type?

    The specific research question being addressed.

    What is simple regression?

    Analyzes the relationship between one predictor and a dependent variable.

    How does standard regression differ from simple regression?

    Standard regression includes multiple predictors to explain variance.

    What defines set-wise regression?

    Involves multiple models to assess the impact of different sets of predictors.

    What is hierarchical regression?

    Adds predictors in steps to evaluate their contribution to model changes.

    What is the purpose of reporting ANOVA in regression?

    Determines if the model significantly predicts variance in the dependent variable.

    What does R² represent in regression reporting?

    Indicates the percentage of variance explained by the model.

    What information is provided by t tests in regression?

    Shows the significance of individual predictors in the model.

    What is the significance of beta coefficients?

    Allows comparison of predictor contributions despite different measurement scales.

    What does reporting set-wise regression involve?

    Comparing multiple models to assess changes in predictive power.

    What is the role of adjusted R² in regression?

    Accounts for the number of predictors when assessing model fit.
