How do you interpret a p value of 0.030? - Answers

p=0.030 means that there is a 3% chance that you are wrong to reject the null hypothesis (H0). In a lot of studies, p<0.05 is considered significant evidence and the H0 is rejected. However, this depends on the research done, sometimes the boundary is set at p<0.01 or even lower. Example: a study tries to see if males are, on average, taller then woman H0: Males do not have a higher average length than women Ha: Males have a higher average length than women P-value is set at 0.05 [Statistical analysis, including a check of all assumptions] p=0.03<0.05 This dataset yielded a p<0.05. Therefore, the H0 is rejected. This study supports the conclusion that males have a higher average length than women
