The 5% (.05) significance level is the widely accepted
criterion for Null Hypothesis Significance Testing.
Discuss some problems with using a strict cutoff to determine
whether your findings were significant. Discuss how you can make
sure that you are presenting your results more fairly/honestly. How
can a confidence interval help with estimating the practical
significance of your results?
