In the results of a hypothesis test, we typically use the p-value to decide if the data support the null hypothesis or not.... Some researchers say that a hypothesis test can have one of two outcomes: you accept the null hypothesis or you reject the null hypothesis.

  • The typical approach for testing a null hypothesis is to select a statistic based on a sample of fixed size, calculate the value of the statistic for the sample and then reject the null hypothesis if and only if the statistic falls in the critical region.
  • How to write a research hypothesis and null hypothesis. If we predict that math s in better performance, than we are predicting that after ent (tutoring), the treated sample truly is different from ted one (and therefore, from a different population).
  • you do not need to reject a null hypothesis. If you don not that means "we retain the null hypothesis." we retain the null hypothesis when the p-value is large but you have … to compare the p-values with alpha levels of .01,.1, and .05 (most common alpha levels).
