Summarize the correlation between the 6 variables for 8^th grade and 9^th grade, respectively (indicate whether the correlations are statistically significant using alpha of .05)

What are the t statistics for comparing the 8^th grade and 9^th grade value of the 6 variables? (indicate whether the t statistics are statistically significant using alpha of .05)

What effect do students' 9^th grade mastery goals have on their mathematics self-efficacy and mathematics GPA?

What effect do students' 9^th grade perceptions of performance-focused classrooms have on their mathematics self-efficacy and mathematics GPA?

Are there significant differences in students' mathematics GPA or mathematics self-efficacy between the students whose parents have at least one mastery goal and the students whose parents do not have any mastery goas?
