The scientific method homework and study guide
In psychological terms, what does “controlled environment” mean?
A controlled experiment isolates the effect of one variable on a system by keeping all the other variables the same except for the one being studied. This is when a theory is put to the test in a scientific way. In a controlled experiment, the cause (the independent variable) is changed in a planned way, and the effect (the dependent variable) is measured. Any other factors are also in charge. The person doing the research can operationalize (i.e., define) the variables being studied so that they can be measured in an objective way. You can look at the quantitative data to see if there are any differences between the experimental group and the control group.
