1. Describe a scenario, with fake data, in which the appropriate statistical test would be a 1-way independent factors ANOVA. Create an ANOVA that includes 4 levels with 5 participants in each level. Present your null and alternative hypothesis for your study in a combination of words and/or symbols. Include the actual (made-up) raw score for each participant.

This is an example for 1 way ANOVA with 4 levels and 5 particiapnts in each.
