Detailed explanation-1: -A one-way ANOVA uses one independent variable, while a two-way ANOVA uses two independent variables. one categorical (DISCRETE) independent variable and one CONTINUOUS dependent variable. ANOVA allows you to examine whether the dependent variable is affected by (depends on) the categories of the independent variable.
Detailed explanation-2: -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.
Detailed explanation-3: -The independent variable is the factor changed in an experiment. There is usually only one independent variable as otherwise it’s hard to know which variable has caused the change.
