Document Summary
Identify and explain the three criteria for establishing cause-and-effect relationships between variables. Discuss the ability to satisfy these criteria when using correlational and experimental designs. Reference: slide 8 from the powerpoint: 3 criteria for establishing cause-and-effect relationships between variables involve: temporal precedence, covariation, elimination of alternative(cofounding) explanations, temporal precedence: cause must precede effect. You must have the cause before the effect. To show that the variable you are examining (the cause) is what possibly led to the effect. You must prove that the cause occurred before the effect showing some association between the two. General, basic example- measuring amount of studying and marks on a test. You must show that the amount of studying comes before the marks on a test. You would study before the test, showing a link between studying and marks. How to prove this criteria in: correlational studies: record the pre-existing conditions since you are monitoring natural groups.
