A researcher intended to investigate the main effects of teaching method (methods 1, 2, and 3), and teacher type (1: liberal; 2: structured) on students’ reading achievement (on a 0 – 10 scale, the higher the better). The researcher was also wondering if there is any interaction effect between teaching method and teacher type on reading achievement. Therefore, in the beginning of the semester, he randomly selected 60 fourth-grade students from the N City then randomly assigned them to 6 groups representing different combinations of teaching methods and teacher types. After one semester, students were measured on reading achievement. Please use the relevant two-way ANOVA results to answer the following questions:
1. Is there any interaction effect between teacher type and teaching method on the reading achievement of fourth-grade students in the N City? Please support your ve
al conclusions with the F test results and the effect size index (1 point)?
2. Is there any main effect of teaching method on the reading achievement of fourth-grade students in the N City? Please support your ve
al conclusions with the F test results and the effect size index (1 point)?
3. Is there any main effect of teacher type on the reading achievement of fourth-grade students in the N City? Please support your ve
al conclusions with the F test results and the effect size index (1 point)?
4. Please copy and paste (a) the Tests of Between-Subjects Effects table (1 point) and (b) the Profile Plot (1 point) from the SPSS outputs onto your submitted assignment.
