How do you feel about the use of animals as research subjects in psychological studies? Back up your position with evidence.

In experimental research, subjects that receive some special treatment in regard to the independent variable are the

Explain why "a correlation does not prove causation".

Design an experiment that will examine the question: "Who will learn more about psychology, those students enrolled in a traditional course or those enrolled in a distance learning course." Be sure to identify: $\bullet$ The independent and dependent variables $\bullet$ Any confounding variables that might need to be controlled. $\bullet$ Your control and treatment groups Also be sure to explain how you will measure the dependent variable

Trevor plans to study the relationship between people's responses to highly stressful situations and their overall health. He decides he must use correlational research, rather than experimental research, to investigate this problem. Trevor most likely chose a correlational method because correlational studies
