Your research question fundamentally determines the statistical test. Here are some common questions and the corresponding tests:
1. Comparing Means: If you want to compare the means of two or more groups, tests like the t-test or ANOVA might be appropriate. 2. Association Between Variables: To examine relationships between variables, you might use correlation or regression analysis. 3. Differences in Proportions: For comparing proportions or frequencies, Chi-square tests are commonly used.
