I need help with these review questions using the following data
Use the StatCrunch database that you created in Week 1. Conduct an ANOVA to determine whether there is a significant difference in the self-esteem scores of participants who are right-handed, participants who are left-handed, and participants who use both hands. Run post-hoc tests even if your findings are not significant. Copy and paste the output into a Word document. Write up your results. Explain whether or not you would report that post-hoc analyses based on your findings. If it is appropriate for you to report the post hoc findings then do so. If it is not appropriate for you to report the post hoc findings then explain how you would interpret the post hoc findings if you were reporting them.
