The p-value is a probability

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). Webb14 okt. 2024 · In this example, the p-value of 0.03 indicates that there’s a 3% probability that the results of your data set are due to chance. The p-value allows you to reject the null hypothesis. Meanwhile, a p-value above the confidence level tells you that there is a higher probability that the observed results in your data set are due to chance.
