WebFeb 3, 2024 · P values are probabilities, so they are always between 0 and 1. A high P value indicates the observed results are likely to occur by chance under the null hypothesis. A low P value indicates that the results are less likely to occur by chance under the null hypothesis. Usually, a threshold is chosen to determine statistical significance. WebJul 13, 2024 · Having just the p-value is not enough, we need to set a threshold (aka significance level — alpha ). The alpha should always be set before an experiment to avoid bias. If the observed p-value is lower than alpha, then we conclude that the result is statistically significant. ti posluš
