In correlational studies a researcher looks for associations among naturally occurring variables, whereas in experimental studies the researcher introduces a change and then monitors its effects.
For instance, a correlational study might look at variables that cannot be manipulated for the purposes of the study. For instance, is height correlated with how much people earn? Or, is intelligence correlated with marital happiness? You would be giving subjects tests and surveys to answer these questions, but could not manipulate the variables. In addition, I don't think that there is a "control group" for comparison purposes.
On the other hand, an experimental study involves comparing two groups - and manipulating the variables. For instance, let's say the question is, "Does caffeine improve test performance?"
Group 1 would have your subjects come to the lab and take some kind of test, making sure that they had had no caffeine within the last 24 hours, or some such scenario.
Group 2 would have the same group of subjects come to the lab, drink a cup of coffee (or something) 20 minutes before taking a similar version of the first test (so there are no practice effects), and then comparing Group 1 and Group 2's scores to see if there was any significant difference.
The correlation method examines the relationship between two variables without manipulating them, while the experimental method involves manipulating one variable to observe its effect on another. Correlation does not imply causation, whereas experimental research can establish cause-and-effect relationships. Experimental research allows for greater control over variables compared to correlational studies, making it better suited for establishing causality.

When is a correlation research method used?
A correlation research method is used to examine the relationship between two variables to see if they are related and how they may change together. It helps to determine if there is a pattern or connection between the variables, but it does not imply causation.
Why is the correlational method even considered if the experimental method is the only research method that identifies cause and effect?
While the experimental method is ideal for determining cause and effect, the correlational method is still valuable for studying relationships between variables when it's not feasible or ethical to manipulate them. Correlational studies can provide useful information about associations between variables and generate hypotheses for further experimental research.
What research method yields the most definite evidence of cause effect conclusions?
Experimental research method yields the most definite evidence of cause-effect conclusions because it involves manipulating variables, controlling extraneous factors, and randomly assigning participants to conditions, allowing researchers to establish a causal relationship between variables.
What advantage does the experimental method have over non-experimental methods of research?
The experimental method allows researchers to establish cause-and-effect relationships by manipulating variables and controlling for confounding factors. This method provides more control over the research setting, increasing internal validity compared to non-experimental methods.
What is the casual-comparative research method?
Casual-comparative research method is a type of research design that involves examining the relationship between variables without manipulating them. It aims to determine if there is a cause-and-effect relationship between the variables being studied. This method is also known as quasi-experimental research.

What are the advantages and disadvantages of correlation method?
The advantage of the correlational research method is the ability to prove a positive or negative correlation between two subjects . The disadvantage of this is the unclear interpreation of cause and affect. moletsane
