When a psychologist simply records the relationship between two variables without manipulating them, it is called a – study. The
observed relationship does not by itself reveal which variable – the other. This is the – problem. Also, the relationship may be due to a – controlling both of the observed variables.
The Correct approach will be "correlational, causes, directionality and third variable".
Explanation:
Correlational studies are little more than an investigation that is sometimes used throughout psychology as either a preparatory method for gathering information about a particular topic and within circumstances where it would not be sufficient to execute a research project.
The method described in the previous section usually includes investigates the relationships between two or even more independent variables.
Because then the answer is indeed the correct one.
