The strengths of the correlational research strategy include that it: 1) can be used to identify relationships between variables that may warrant future experimentation, 2) allows a researcher to investigate variables that are not possible to manipulate, 3) has high external validity. Weaknesses of the correlational strategy include that it: 1) cannot assess causality, 2) third-variable problem, 3) directionality problem, and 4) low internal validity.

In a negative relationship there is a tendency for increases in one variable to be accompanied by decreases in the other variable. The two variables tend to move in opposite directions.

A correlational study produces two scores for each individual. The scores can be shown in a graph known as a scatter plot. The value of a scatter plot is that it allows you to see three aspects of the relationship between the two variables: the direction, the form, and the strength of the relationship.
