Comparative Experiments is testing two variables by designing a experiment.This can be designed to collect data on different/objects/events or collect data under different condition to test the hypothesis.
It contains a testable hypothesis where we have at least one independent variable and one dependent variables and a control group. These experiments are usually designed to test the relationships between independent and dependent variable. Data can be collected here by both quantitatively and/or qualitatively to draw conclusions and can support/reject the hypothesis.
Once the results are received of the comparative experiment, the scientist can compare the difference in the dependent variable C for each (independent variable) treatment, concluding either one (independent variable) treatment is more effective than the other or that both independent variable(treatments) have the same effectiveness.
