Question

give an example when you would use both experimental and correlational study?

Answer 1

Answer:

Correlational and Experimental Study:

In correlational studies a looks for associations among naturally occurring variables, whereas in experimental studies the introduces a change and then monitors its effects.

Example of when we use both Correlational and Experimental Study:

Example:

A health magazine reports that depressed people who continue medication for at least six months are less likely to relapse than are people who take medication for less than six months. What would you need to know about the design of this study, in order to interpret the report?
Explanation:
Here, enough information to see whether it was a correlational study or an experiment.
In a correlational study, we would take advantage of the fact that some depressed people stay on medication longer than others. Suppose we finds that people on medication more than six months are less likely to relapse. Then we cannot conclude that the increased time on medication improved the relapse rate because other explanations have not been ruled out.
In an experimental study, we controls how long people stay on medication. Half of a sample of depressed people is randomly chosen to receive medication for less than six months; the others receive medication for more than six months. The only way the two groups differ is in the duration of the medication.
