ANOVA scales T-tests to new heights. There are two main types of ANOVA: One-way ANOVA - It evaluates the impact of a single factor (group) on a single response variable. By doing so, it determines if all the samples are the same or not. One-way ANOVA is quite limited, as it ...
To report the results of the test, it is useful to provide the t statistic, degrees of freedom and P value at the end of the sentence. For example, we could write: IBM SPSS version used: 24 RELATED ARTICLES Excel How To Perform A One-Way ANOVA Test In Microsoft Excel ...
Note: If you have unbalanced (unequal sample size for each group) data, you can perform similar steps as described for one-way ANOVA with balanced design (equal sample size for each group). From ANOVA analysis, we know that treatment differences are statistically significant, but ANOVA does no...
How to perform the Kruskal-Wallis test in R, when there are more than two groups, the Kruskal-Wallis test by rank is a non-parametric alternative to the one-way ANOVA test. It extends the two-samples Wilcoxon test. When the assumptions of the one-way ANOVA test are not met, this meth...
