The use of statistics to assess the probability of a given assumption being accurate is hypothesis testing. The typical hypothesis testing process is made up of four stages.

Recognize a test metrics which can be used to determine the null hypothesis truth.
Calculate the P-value, that is the likelihood that if the null hypothesis is true, a test result would be obtained at least as large as the one observed.
Measure the p-value with an appropriate alpha value.
