The independent variable in a research is that factor that the researcher changes or controls on purpose in order to find out its effect. From the example, the researcher wanted to understand the effect of red room and blue room on the eating level of participants, hence what he is changing or controlling is the color of the decoration in the room and hence that is the independent variable.
