Homework Answers
Cohen's f2 = r2 / (1 - r2)
and is interpreted as 0.02=small, 0.15=medium, 0.35=large
here the value is 0.22. Thus the result is statistically significant. Hence we can say that:
The additional variance explained at Step 2 is statistically significant.

Suppose a regression analysis produces an R2 coefficient of .51. What can we conclude from these results? The model is not useful. The model explains a very small amount of the variation in the dependent variable. The model explains most of the variation in the dependent variable. The model is not statistically significant.

You conduct a standard multiple regression (SMR) analysis with two predictors (X1 and X2), which account for 25% of the variability in the criterion (Y). However, the shared variance between X1 and X2 accounts for 0% of the variance in the DV. If both IVs are entered together in a standard multiple regression, the coefficient for X1 will be compared to the coefficient that X1 would produce if X1 was entered in Block 1 of a hierarchical multiple regression (HMR),...

Suppose that you estimate a regression model with a sample size of 92 observations and 10 explanatory variables, including the intercept, using ordinary least squares and the residual sum of squares from this estimated model is 22. You then conduct a Ramsey’s RESET on this model and the residual sum of squares from the Ramsey regression is 20. The test statistic associated with this Ramsey’s RESET is ______, and you can conclude at the 5-percent level of significance that _________________....
