p-value

p-value

P-value is the likelihood that a value more extreme than our sample statistic would be generated from the empty model; a number between 0 and 1; a small p-value (e.g., ≤ 0.05) indicates our sample would be "unlikely" given the null hypothesis, so you reject the null hypothesis and a large p-value (e.g., > 0.05) indicates our sample would be "likely" against the null hypothesis, so you fail to reject the null hypothesis.
