P value less than 0.05

WebA p-value less than or equal to 0.05 does not indicate that the groups are definitely different. Instead, it suggests that the null hypothesis is probably not true and provides guidance to reject the null hypothesis and accept the alternative hypothesis, i.e. that the groups probably differ. WebThe p-value indicates how probable the results are due to chance. p=0.05 means that there is a 5% probability that the results are due to random chance. p=0.001 means that the chances are only 1 in a thousand. The choice of significance level at which you reject null hypothesis is arbitrary. Conventionally, 5%, 1% and 0.1% levels are used.
