Q

correlation

A

the relationship between two or more variables; when two variables are correlated, one variable changes as the other does

Q

experiments

A

designed to test hypotheses in a controlled setting in efforts to explain how certain factors or events produce outcomes; the only research method that measures cause and effect relationships between variables

Q

negative correlation

A

two variables change in different directions, with one becoming larger as the other becomes smaller; a negative correlation is not the same thing as no correlation
