A large p -value (> 0.05) indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis.
WebbA. The P-value of a test is the probability of obtaining a result as extreme (or more extreme) as the one obtained assuming the null hypothesis is false. B. If the P-value for a test is 0.015, the probability that the null hypothesis is true is 0.015. C. The larger the P-value, the more evidence there is against the null hypothesis. D. WebbThe most common errors are mistaking a low p-value with evidence for lack of effect or difference, mistaking statistical significance with practical significance, as well as treating the p-value as a probability, related to a …

WebbThe p-value corresponds to the probability of observing sample data at least as extreme as the actually obtained test statistic. Small p-values provide evidence against the null hypothesis. The smaller (closer to 0) the p-value, the stronger is the evidence against the null hypothesis.
Webb, the p-value = 0.03, then the probability of randomly selecting a sample of 100 users who spend, on average, 25 minutes on the yellow-background website is only 3%!
