You have noticed that UMD students seem to drink more coffee (on average) the longer they have been in school. To study this question, you survey 200 students and obtain their average weekly coffee intake. Data are collected using a between-subjects approach on 50 Freshmen, 50 Sophomores, 50 Juniors, and 50 Seniors. The data are presented in terms of how many cups of coffee, on average, each class drank per week. Here is what was found: Freshmen (M= 11.5, SD=3.1) Sophomore (M= 12.1, SD=2.2) Junior (M= 15.3, SD=2.5) Senior (M-19.8, SD=3.0) F(3,196)= 6.5, p = .004, n² = .32, Tukey's HSD = 2.4 Based on the nature of the independent variable and design of the study, what statistical test should have been used? OA. Dependent (paired samples) t-test OB. One-way ANOVA OC. Independent samples t-test Save Answer O D. Repeated Measures ANOVA
