Quizplus · Accepted Answer

The alternative hypothesis represents a statement of a relationship between variables or a difference in groups that a researcher is interested in proving. However, in hypothesis testing, we can never definitively prove the alternative hypothesis to be true; we can only reject the null hypothesis based on the data, which suggests that there is evidence to support the alternative hypothesis. The nature of statistical testing is such that it deals with probabilities and not certainties, meaning we can only say that the data are consistent with the alternative hypothesis to a certain degree of confidence.
