Hi There are various canned experiments out there (e.g., stroop task). Personally, as someone who has taught such a course for a number of years, I would avoid the actual data collection (assuming this is not a combined methods / stats class) and give an artificial data set as the result of some within-s design (e.g., pre, post, follow-up; control, placebo, drug; ...) with the data chosen to allow for ease of computation of various terms: SS treatment, SS subjects, and SS txs (the error term). I don't do within-s until after doing the between-s factorial, so that students understand idea of an interaction by the time we cover within-s. You don't mention what stats package you use, but with SPSS I will also present data in between-s format (codes for treatment and subjects, plus single data value) to show students that default factorial uses all df and that txs is error for within-s analysis. Proper analysis emerges from GLM or MANOVA with /DESIGN treatment subjects, rather than default factorial. I have sample data like this, but not handy right now as I am on the road. Return home tonight if you are interested in it. Take care Jim James M. Clark Professor of Psychology 204-786-9757 204-774-4134 Fax [email protected]
>>> Michelle Everson <[email protected]> 06-Mar-11 12:08 PM >>> Hello, First, I apologize for the cross-posting. I'm looking for a quick in-class activity I can do (in an intermediate statistics course) in order to introduce my students to the repeated-measures (or one-way within-subjects) ANOVA. I have a relatively small class (21 students) and we meet in a computer lab. I was hoping to do something in class that would yield some data that we can then explore and analyze right on the spot. Does anyone have any good suggestions? One thought I had was something where students could work through puzzles of some kind on the computer (where the DV would be the amount of time taken to complete the puzzle). Ideally, I wanted at least three different conditions for them to work through, but we could have just two. I'm just not sure if there is a website out there that might give me what I need to pull this off (by Wednesday!). Also, I have some students in class for whom English is a second language, so I want to avoid tasks that could be very challenging or frustrating for those students (e.g., I was initially thinking of word puzzle activities like Boggle, but I think that would be too much for some students). Thank you so much for any ideas you might have to share.
