Conduct an independent samples t-test (a.k.a., between-subjects design, which is discussed in Ch. 10, and will be covered in Week 9 of this course) comparing two independent groups on any variable of your choice.
Each sample should have at least n=10 individuals (thus, 20 participants in the study total, at minimum)
What to turn in:
State your research question (e.g., Is there a difference in coffee consumption between males and females?).
State the null and alternative hypotheses, and then conduct the hypothesis test using an alpha level of .05.
Calculate and interpret a measure of effect size (estimated Cohen’s d or r2).
Write a conclusion statement, as would appear in a published research report.
