For that reason, all hypotheses have an opposite called the null hypothesis. If our hypothesis states that we believe there is some difference between our control and treatment, the null hypothesis states its opposite: There is NO difference. Instead of “innocent until proven guilty,” we assume “Null until proven otherwise.”

Chris Stucchio does a great job explaining the difference between the two tests in context: “In frequentist tests, you have a null hypothesis. The null hypothesis is what you believe to be true absent evidence to the contrary. Now suppose you’ve run a test and received a p-value. ” ( quote source ).

A p-value is the measure of evidence against the null hypothesis (the control, in A/B testing parlance). The p-value is the probability of seeing the current result or a more extreme one given that the null hypothesis is true. To start with, let’s go over p-values , which are also very misunderstood.
