Two-Group Parametric Hypothesis Testing
... 1. In the Independent Samples Design (also known as the between-subjects design) the observations in the one group are independent of those in the other group. If the research is experimental, we not only randomly select our subjects but we also randomly assign them to the treatment groups – thus, t ...
