Detailed explanation-1: -When to use a one-way ANOVA. Use a one-way ANOVA when you have collected data about one categorical independent variable and one quantitative dependent variable. The independent variable should have at least three levels (i.e. at least three different groups or categories).
Detailed explanation-2: -In the One-way ANOVA, there is only one dependent variable – and hypotheses are formulated about the means of the groups on that dependent variable.
Detailed explanation-3: -Identify the independent and dependent variables in a research problem. The independent variable is the variable that is used to explain, cause, or predict the dependent variable. The dependent variable is the effect, or the variable to be predicted.
