The hypothesis which is to be tested is the null hypothesis, whereas the alternative hypothesis offers an alternative to the null hypothesis. The null hypothesis is a statement in which there is no relationship between two variables. An alternative hypothesis is a statement in which there is some statistical worth between two measured phenomena.

Testing for the null hypothesis is indirect and implicit. Testing for the alternative hypothesis is direct and explicit. The null hypothesis is represented by H zero. The alternative hypothesis is one. The mathematical formulation for the null hypothesis is an equal sign. Testing for the alternative hypothesis is the unequal sign. With the null hypothesis, if there are no changes in opinions or actions, then no alteration is made. With the alternative hypothesis, if the alternative is accepted, then adjustments are made.
