The first step in hypothesis testing is to formulate two opposing hypotheses, called the null and the alternative hypotheses. The null hypothesis is the default position that there is no effect or difference between the groups being compared. The alternative hypothesis is the opposite of the null hypothesis and asserts that there is indeed an effect or difference between the groups being compared. Once these hypotheses are formulated, the remaining steps involve performing statistical tests to determine whether the null hypothesis can be rejected or not.
