Statistical Data Analysis: p-value. In statistical hypothesis testing we use a p-value (probability value) to decide whether or not the sample provides strong evidence against the null hypothesis. The p-value is a numerical measure of the statistical significance of a hypothesis test. It tells us how likely it is that we could have gotten our sample data (e.g., 10 heads) even if the null hypothesis is true (e.g., fair coin).
