Within each group there should be three or more observations here, this means walruses , and the means of the samples are compared. However, in the two-way ANOVA each sample is defined in two ways, and resultingly put into two categorical groups.
The two-way ANOVA therefore examines the effect of two factors month and gender on a dependent variable — in this case weight, and also examines whether the two factors affect each other to influence the continuous variable. Because the two-way ANOVA consider the effect of two categorical factors, and the effect of the categorical factors on each other, there are three pairs of null or alternative hypotheses for the two-way ANOVA.

Here, we look at data integrity in the context of shared data and introduce some procedures that will mitigate against miscommunication. Like what you just read? You can find similar content on the communities below.
What is a One-Way ANOVA?
The null hypothesis H0 is that there is no difference between the groups and equality between means. Walruses weigh the same in different months The alternative hypothesis H1 is that there is a difference between the means and groups. Sample independence — that each sample has been drawn independently of the other samples Variance Equality — That the variance of data in the different groups should be the same Normality — That each sample is taken from a normally distributed population What are the hypotheses of a Two-Way ANOVA?
The means of all month groups are equal H1: The mean of at least one month group is different H0: The means of the gender groups are equal H1: See more words from the same year. More Definitions for one - way.
