Question

Which of the statements about one-way ANOVA is FALSE? ANOVA deals only with one factor, such as treatment or group. There can be any number of levels in one-way ANOVA. The purpose of one way ANOVA is to verify whether the data collected from different sources converge on a common mean. It is used when there are two independent variables in the experiment.

Answer 1

It is used when there are two independent variables in the experiment.

Explanation:

The one way analysis of Variance statistical test is employed when we intend to analyze the variation in the mean of levels or groups of an independent variable. It allows us check for convergence of data. The variable here is usually categorical and must have 3 or more levels, hence, the groups could be infinite in count. A one way ANOVA will have only ONE independent variable, For data with two independent variables, the TWO way ANOVA statistical test is employed.
