What is the main difference between a one-way and a two-way analysis of variance?
A) a one-way analysis of variance is used when you have one independent variable and a two-way analysis of variance is used when you have two independent variables
B) one-way is used when you have matched groups and two-way is used when you have independent groups
C) one uses a one-way when working with an odd number of independent variables and a two-way when working with an even number

A one-way analysis of variance (ANOVA) is used when there is one independent variable, and a two-way ANOVA is used when there are two independent variables. This distinction allows for the analysis of the effect of each independent variable on the dependent variable, as well as the interaction effect between the two independent variables in the case of a two-way ANOVA.
