We compare a P-value to a significance level to make a conclusion in a significance test. Given the null hypothesis is true, a p-value is the probability of getting a result as or more extreme than the sample result by random chance alone. If a p-value is lower than our significance level, we reject the null hypothesis.

However, if your p-value is say 0.02, there’s only a very small chance you would have obtained that data if the null hypothesis was in fact true. And since the p-value is a probability just like alpha, p-values also range from 0 to 1.
