Using this information and your summary data, complete an ANOVA Summary Table and interpret pairwise comparisons. BEFORE ANSWERING QUIZ QUESTIONS, COMPLETE YOUR ANOVA TABLE BELOW (Table 2). Scenario: A study by Blackwell, Trzesniewski, and Dweck (2007) measured mindset of junior high students at the beginning of 7th grade, as well as the amount of time the students spent on their math homework, measured in minutes. Mindset was divided into three groups: those who had mostly growth-mindset beliefs, those with a mixed-mindset (some growth beleifs and some fixed beliefs), and those with mostly fixed-mindset beliefs. The descriptive statistics for the estimated time spent studying math in minutes for one day for the three different mindset groups in Table 1 were provided by statistical software.
