The residual plot below suggests which violation(s)of regression assumptions? 
A) Autocorrelation 
B) Heteroscedasticity 
C) Nonnormality 
D) Multicollinearity

Quizplus · Accepted Answer

The residual plot shows a clear pattern of increasing variance as the predicted values increase, suggesting heteroscedasticity. There is no evidence of autocorrelation or multicollinearity and it is difficult to assess nonnormality from a residual plot.
