Cause-and-effect conclusions can be drawn from the results of an experiment because the independent variable, the variable that is manipulated or changed, is held constant while other possible causes of change in the dependent variable are controlled. This helps establish a relationship between the two variables and determine if the change in the independent variable caused the change in the dependent variable. Statistical analysis can be applied to the data to further support the cause-and-effect relationship. The setting and size of the sample group are not determining factors in drawing cause-and-effect conclusions.
