Answer 1

what is the difference between experimental research and correlational research

Experimental research: A type of research design in which the experimenter manipulates the independent variable as he wants to be called experimental research. It builds cause and effect relationships between variables.

Correlational research: A type of research design which allows the researcher to define the strength of the relationship between variable. In this research, the researcher can't manipulate the independent variable.

Difference between experimental research and correlational research:

Experimental research design	Correlational research design.
1) The experimenter can manipulate the independent variable	1) The researcher can't manipulate the independent variable
2) It tells cause and effects relationship between variables	2) It never tells cause and effects relationships between variables.
3) It will have a control group and an experimental group	3) It doesn't have a control group and an experimental group
4) Confound variables are in the control of the experimenter.	4) Confound variables are not in the control of the researcher.
5) It uses alpha value to define the relationship	5) It uses the correlation coefficient to define the relationship.

which research type do you think would have more accurate results or is it better?

I think the experimental type of research is better. Because It builds a causal relationship between variables. Experimental research design controls confound variables. So that the internal validity of experiments is higher than correlation studies. The experimental design sample represents the population. So that the external validity of the experiments is higher than correlational studies. That's why I think the experimental research type is better than correlational studies.
