ANSWER
Independent variables are the factors that a researcher manipulates or changes in order to study their effect on the dependent variable. In other words, independent variables are the cause in an experiment. Dependent variables are the factors that are being measured or observed in an experiment. They are called dependent because their values depend on the values of the independent variables. Extraneous variables are factors that may affect the outcome of an experiment, but are not being studied.
One way that researchers attempt to control extraneous variables is by using a control group. A control group is a group of participants who are similar to the experimental group in every way except for the factor being studied. The control group allows researchers to compare the effects of the independent variable on the dependent variable by comparing the results from the experimental group to the results from the control group.
Another way that researchers attempt to control extraneous variables is by using random assignment. This means that participants are randomly assigned to either the experimental group or the control group. This helps to ensure that the groups are similar, and reduces the likelihood that extraneous variables will affect the results. By using a combination of a control group and random assignment, researchers can better isolate the effects of the independent variable on the dependent variable.
