I am planning a small research proposal as a part of one of my masters' units. The broead topic of the proposal is social differences in students' academic achievement. I am interested in investigating whether there is a correlation between peer victimization and Academic achievement, using a test of relationships (Pearson, Spearman, Kendall etc.) The sample will be students from ethnic minority groups. My variables will be peer victimization which will be the independent variable and academic achievement which will be the dependent variable. I was thinking of include race/ethnicity as a third variable but if I do so, I don't know which will be the appropriate test for testing the relationship of all three variables.
Can you spot any drawbacks on the research design or in the Research Question?
Is there any reliable and valid measurement for primary school students' academic achievement?
I would appreciate that, because I am a novice in research.
