In experiment,the treatment is called ______.

A) dependent variable
B) independent variable
C) intervening variable
D) mediating variable

In an experiment, the treatment is the independent variable because it is the variable that is manipulated by the researcher to see if it has an effect on the dependent variable. The dependent variable is the variable that is measured to see if it is affected by the independent variable. Intervening variables and mediating variables are other types of variables that can impact the relationship between the independent and dependent variables, but they are not the same as the treatment.
