In statistical hypothesis testing, the alternative hypothesis (H1) is a statement that is the opposite of the null hypothesis (H0). It represents the researcher's hypothesis that there is a significant difference, effect, or relationship between variables being studied. For example, if the null hypothesis states that there is no difference in test scores between two groups, the alternative hypothesis would assert that there is a significant difference in test scores between the two groups. The alternative hypothesis is typically denoted as Ha in statistical notation.
