What part of an experiment is manipulated? Independent variable The part of the experiment that is manipulated or changed
How Variable Is Handled Or Manipulated In Quasi-experimental Research Design? In quasi- experimental research the researchers do not manipulate or control an independent variable, nor do they randomly assign participants to groups. In fact, in quasi- experimental research there are no strict independent or dependent variables, since it is not clear as to what actually
What Are The Levels Of An Independent Variable? Levels of an Independent Variable If an experiment compares an experimental treatment with a control treatment, then the independent variable (type of treatment) has two levels: experimental and control. What is provided by the independent variable? The independent variable is the variable the experimenter manipulates or changes,
