Successfully navigate to the 'SPSS Stepwise Regression – Simple Tutorial' page. Correctly identify the primary purpose of stepwise regression as stated in the introductory text (e.g., 'to build a regression model by automatically adding or removing predictors based on statistical criteria'). List at least two correct key assumptions or conditions for stepwise regression (e.g., 'large sample size', 'normal distribution of residuals', 'linearity', 'homoscedasticity', 'independence of observations', 'no multicollinearity', 'variables should be measured at interval or ratio level').
