The most common statistical analysis for a single-factor two-group design is the independent-measures t-test. This is because it allows for comparison between the means of two groups while controlling for individual differences within each group. ANOVA is used for designs with more than two groups, repeated-measures t-test is used for within-subjects designs, and regression analyzes the relationship between variables.
