A statistical hypothesis, sometimes called confirmatory data analysis, is an assumption about a population parameter.
A hypothesis is a tentative statement about the relationship between two or more variables. For example, a new technology or theory might make the necessary experiments feasible. For instance, to avoid having the sample size be too small to reject a null hypothesis, it is recommended that one specify a sufficient sample size from the beginning. "[7] In this sense, 'hypothesis' refers to a clever idea or to a convenient mathematical approach that simplifies cumbersome calculations.
