A researcher who also happens to be teaching a course is interested in the environmental factors around final exams. She wants to test the research question "do different colours of paper affect a student's performance under exam conditions?". The researcher hypothesises that aggressive colours such as red will impact on a student's ability to focus (leading to a lower grade) whereas calming colours such as green will improve attentiveness (leading to a higher grade). She prints a third of that year's final exam on red paper, another third on green paper, and the last third on standard white paper to use as a control. That year's cohort sit their final exam in one of these conditions, however the researcher also intends to repeat the same experiment the subsequent year with a new cohort (and will add these cases to the dataset before analysis). What would be the most appropriate statistical technique to use to test the above? Question 29Select one: a. A Mixed ANOVA (with Time as an IV) b. A One-Way ANOVA c. A Repeated-measures ANOVA d. A Three-way ANOVA
