e depends on experiment

The number of independent variables an experimenter should manipulate in one experiment can vary depending on the specific goals and design of the study. In many cases, it's common to manipulate one independent variable to maintain clarity and control, but in some experiments, especially more complex studies, researchers may manipulate multiple independent variables to investigate interactions or the effects of different factors. Therefore, the appropriate number of independent variables depends on the specific research question and experimental design.
