Assignment Name: Comparing Two or More Groups Essay

Questions

#1.) Provide an example of a hypothetical study that would use a one-way between-subjects ANOVA. Be sure to describe the different groups, conditions, and hypotheses involved. What would the null be and does successful rejection indicate a mean significantly different from every other mean? How would you decide on the necessary sample size (one which provides adequate statistical power)?

#2.)State two common post hoc procedures for the comparison of means in an ANOVA. How do these differ from planned contrasts? Given a situation where a researcher intends to demonstrate that a treatment variable will have a significant difference on outcomes, which would the research want to be larger: MS between or MS within? Explain.
