Do some study planning for a project of your own (this can be your A-level project for this class, your dissertation project, or something else). What's the smallest effect size of interest in your study? How many participants, items, etc., will you need? (These latter determinations could be based on actual power analysis from online power calculators, or—more likely—based on trying to maximize your power using the strategies described in the last section of the "power analysis" activity.)
