WebbIf the null hypothesis is true, a p-value of 0.01 indicates that there is a 1% probability of detecting the findings or more severe outcomes. Hence, there is a 99% confidence level that the findings are statistically significant and a 1 in 100 probability that the results were acquired only by chance (i.e., not due to chance). WebbA p -value can indicate the degree of compatibility between a dataset and a particular hypothetical explanation (such as a null hypothesis). Specifically, the p -value can be …

WebbIf the p-value is equal to or smaller than the significance level (α), it suggests that the observed data are inconsistent with the assumption that the null hypothesis is true and thus that hypothesis must be rejected (but this does not automatically mean the alternative hypothesis can be accepted as true).

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. WebbGraphically, the p value is the area in the tail of a probability distribution. It’s calculated when you run hypothesis test and is the area to the right of the test statistic (if you’re …
