Hypothesis Testing: Factorial ANOVA Hello! So I had to propose a research design as an assignment and I chose to look at cognitive function in an exercise group vs. a control group over the period of 10 years. -subjects are tested at the beginning and end of each year The groups were...
If ART = FALSE, then an ANOVA is used. Like the sic function, mic.test takes response times from each of the salience conditions as input. It then returns the exact p-value and test statistic from the chosen test. Example 1 demonstrates the use of the sic function applied to data ...
