How to create a histogram in JMP?ħ.1 Comparing groups in a single variable. Typically, a one-way ANOVA is used when you have three or more categorical, independent groups, but it can be used for just two groups (but an independent-samples t-test is more commonly used for two groups). It tests the effect of two factors at the same time. It is utilized to observe the interaction between the two factors. For example, a two-way ANOVA allows a company to compare worker productivity based on two independent variables, such as department and gender. With a two-way ANOVA, there are two independents. One-way ANOVA: Testing the relationship between shoe brand (Nike, Adidas, Saucony, Hoka) and race finish times in a marathon.

The Student’s t test is used to compare the means between two groups, whereas ANOVA is used to compare the means among three or more groups.
When should you use ANOVA instead of t-tests? One-way ANOVA is typically used when you have a single independent variable, or factor, and your goal is to investigate if variations, or different levels of that factor have a measurable effect on a dependent variable.
