After reading the article carefully and taking notes, answer the following three questions in your initial response
1. What do the overall results (of the various models) tell us about how school gardens affect student academic achievement?
2. Looking specifically at the regression analyses that involve step-wise regression (same DV but different combinations of IVs for different models, e.g., Model 1, Model 2, etc.), what do you learn from these analyses about the importance of using step-wise regression for examining the effects of different IVs/sets of IVs? In other words, what do these analyses reveal about why we don’t just include all of the variables into a single model from the start?
3. Thinking sociologically, what other variables might it have been good to include as controls in the regression analyses?
