The researcher is interested in comparing the impact of three different levels of work attire (casual, dress-casual, and formal) on work performance. Since each participant experiences all three levels of attire, this is a within-groups design. Additionally, since the researcher is comparing three different levels of attire, a one-way ANOVA is appropriate. Therefore, one-way within-groups ANOVA is the best choice for this design.
