File name | Null and Alternative Hypotheses - Basic Concepts |
File Description | In this video we discuss the basic conceptual background of the null and alternative hypotheses. This is one of those topics that frequently drives intro stats students crazy. Therefore I try to place the null and alternative in the context of everyday life and by using a couple examples.The null hypothesis is what we are attempting to overturn by our hypothesis test. We hope to obtain a small enough p-value that we are justified in rejecting the null hypothesis.The alternative or experimental hypothesis reflects that there will be an observed effect for our experiment. In a mathematical formulation of the alternative hypothesis there will typically be an inequality, or not equal to symbol. This hypothesis is denoted by either Ha or by H1. |
