WebThe hypotheses of interest in an ANOVA are as follows: H 0: μ 1 = μ 2 = μ 3 ... = μ k H 1: Means are not all equal. where k = the number of independent comparison groups. In this example, the hypotheses are: H 0: μ 1 = μ 2 = μ 3 = μ 4 H 1: The means are not all equal. The null hypothesis in ANOVA is always that there is no difference in means. After developing your initial research hypothesis (the prediction that you want to investigate), it is important to restate it as a null (Ho) and alternate (Ha) hypothesis so that you can test it mathematically. The alternate hypothesis is usually your initial hypothesis that predicts a relationship between variables. The null … See more For a statistical test to be valid, it is important to perform samplingand collect data in a way that is designed to test your hypothesis.
