pick out the experimental designs behind some of Dr. Bloom's examples and see if you could take one of those.use examples from his talk, so pick whatever interests you and then more formally describe that study design by following the outline below:

1. What is your research question?
2. What is the independent variable and what is the dependent variable
3. What are the levels and how many are there? (remember that if you only have 2 levels, you can just use a t-test. However and FYI, any time you use an independent samples or paired t-test, you can also use a One-Way Anova or repeated measures One-Way Anova instead because the statistical significance of the results will be the same. One reason to use the One-Way Anova, even for two group/mean comparisons is that the SPSS dialog box options let you choose more options like charts, effect size, and power estimates whereas the t-test output options are more limited.)
4. What scale of measurement is associated with a) your independent variable, b) your dependent variable
5. Briefly, how might you design and run the study? You would of course analyze it with Anova, so when you get to explaining your analysis, list your null hypothesis and explain how you would use the Anova F-test results to decide whether or not to reject the null hypothesis.
