Specify the null and alternative hypotheses
WebThe null hypothesis in ANOVA is always that there is no difference in means. The research or alternative hypothesis is always that the means are not all equal and is usually written in words rather than in mathematical symbols. The research hypothesis captures any difference in means and includes, for example, the situation where all four means ...

WebThe null hypothesis is often an initial claim that is based on previous analyses or specialized knowledge. Alternative Hypothesis (H 1) The alternative hypothesis states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. WebThe null hypothesis is generally the complement of the alternative hypothesis. Frequently, it is (or contains) the assumption that you are making about how the data are distributed in order to calculate the test statistic. Here are a few examples to help you understand how these are properly chosen.
WebHere, both null and alternative hypotheses are simple since mean and variance are sufficient to completely specify a normal distribution. The maintained hypothesis in this case is that H;θ ∈{1,2}.
