(10 Marks) Generate a research scenario where you create a data set of 30 participants, and use a t-test for a single -sample to analyze the data. You’ll need to be very clear about why you are using this test – so your Introduction is really important. 2. (10 Marks) Generate a repeated measures research scenario w here you create a data set of 30 participants. Use the appropriate t -test to analyze your findings. 3. (10 Marks) Ge nerate a research scenario of 48 participants that should be analyzed using a t-test for independent means . See your class notes for an example. Part 2 : ANOVA 1. (10 Marks) Generate a research scenario of 40 participants where a one -way ANOVA needs to be employed. Your data must produce a significant overall result, and t here should be a post -hoc test performed and interpreted . 2. (10 Marks) Generate a 2X2 factorial research scenario of 40 participants. Your interaction must be significant . Be sure to produce all cell and marginal means and explain all interactions and main effects. A graph of the interaction is expected too. Part 3 : Nonpar ametric test 1. (5 Marks) Generate a research scenario of 30 participants where a chi -square test for goodness of fit must be used. 2. (5 Marks) Generate a research scenario of 30 participants where a chi -square test for independence must be used. 3. (5 Marks) Generate a research scenario of 30 participants where a Mann -Whitney U test needs to be used.
