Once you know the statistical test youll be using, you can write your hypotheses in a more precise and mathematical way specific to the test you chose. A statistical hypothesis is an assumption about a population parameter. They are also mutually exclusive, meaning that only one can be true at a time. It claims that theres an effect in the population. The null and alternative are always claims about the population. Its essential to scientific research because it serves as a compass for scientists or researchers in carrying out their experiments or studies.
