Step 3: Now that you have conducted the analysis, answer the following questions:
- What is the R-square value for the regression model?
- What does the R-square value tell you about the regression model?
- What is the significance F value of the model?
- What does the significance F value tell you about the statistical significance of the model?
- What is the coefficient (t stat value) for the X-variable drug arrests?
- What does the coefficient (t stat value) mean? In other words, how do you interpret the coeffficient?
- What is the p-value for the X variable drug arrests?
- What does the p-value for drug arrests tell you about its ability to predict prison incarcerations at a level of statistical significance?
- Is the residual plot a random pattern, nonrandom U pattern, or an inverse U pattern?
- What does the type of pattern tell you about the “fit” of the regression model to the data?
