The Alternative Hypothesis, known as Ha, is a form of hypothesis that assumes there is a statistically significant difference between two or more data samples. In any hypothesis test, if there is a less than 5% probability that the difference is due to chance, then the Null Hypothesis is rejected and the Alternative Hypothesis can be pursued.
