1.Why/When do we use a correlation or regression procedure instead of a crosstab procedure?

2. Which PRE Statement below goes with Which MOA:

a. By knowing one's sex, we reduce our errors by 13.7% in predicting attitudes towards sports --- Which MOA are we using this type of statement with (R, Lambda/Gamma/Phi)?_________________

b. We see 13.7% of the variation in attitudes towards sports is being explained by the variation in one's marital status.--- Which MOA are we using this type of statement with (R, Lambda/Gamma/Phi)?_________________

3. What do we need to do to "r" in order to use it in a PRE interpretation (out of ALL the MOAs (R, Lambda, Gamma, Phi, and V), R and PHI need this to be used in the PRE sentence)?

4. Is r or r²used to determine the strength of the association?

5.What are the following and How do they relate to each other: slope, y-intercept, and regression line?

Please find an example on the internet where they used either 1) a scattergram/scatterplot with a Line of Best Fit - what was the apparent association between variables - direction or 2) they used the Pearson's r in the analysis. What was the approximate strength? briefly summarize variables/relationships with this
