You conducted a t-test in your 691 capstone research. You did not find a statistically significant difference between your groups even though your sample size was relatively small. Upon conducting a post hoc power analysis you found that your actual power was 0.57. What should you do? Is there a problem with having a power less than 0.80 when you do not have significant differences?
