Discussion 8 - How is rejecting the null hypothesis related

Discussion 8

One of the most challenging things for students to understand is what it means to reject the null hypothesis. How is rejecting the null hypothesis related to statistical significance? Please use your own words (very important!) to describe what information you use to determine statistical significance, and give an example of this information (for example, how might you check to see if your oneway ANOVA is significant? How about a Two-Way ANOVA?). Once you decide that an effect is significant, for example, please indicate what that means to you IN YOUR OWN WORDS. The point of this discussion is to help you help each other learn, not to copy down a perfect answer. Finally, do you see any problems with/limitations of NHST? Why or why not?
