Reject null if p value is
WebA p-value is the probability that you would obtain the effect observed in your sample, or larger, if the null hypothesis is true for the populations.P-values are calculated based on your sample data and under the assumption that the null hypothesis is true. Lower p-values indicate greater evidence against the null hypothesis. WebA small \(p\)-value is an indication that the null hypothesis is false. Good practice: It is good practice to decide in advance of the test how small a \(p\)-value is required to reject the test. This is exactly analagous to choosing a significance level, \(\alpha\), for test. For example, we decide either to reject the null hypothesis if the ...
