Questions and Answers

Why is homogeneity of variance (homoscedasticity) important in statistical analysis?

  • It ensures that the errors in prediction are consistent across different values of the independent variable (correct)
  • It allows errors in prediction to vary widely across different values of the independent variable
  • It has no impact on the accuracy of statistical analysis
  • It makes statistical analysis more complex and difficult to interpret
  • What does homogeneity of variance (homoscedasticity) refer to?

  • The changing size of the error in prediction across different values of the independent variable
  • The size of the error in prediction being dependent on the dependent variable
  • The complete absence of errors in prediction across different values of the independent variable
  • The consistent size of the error in prediction across different values of the independent variable (correct)
  • What happens when homoscedasticity is violated in statistical analysis?

  • The assumptions underlying many statistical tests are violated (correct)
  • The accuracy of predictions becomes more reliable
  • The analysis becomes less prone to errors
  • The impact on statistical analysis is negligible
  • How does heteroscedasticity differ from homoscedasticity?
