In terms of quantitative study, what is correlational research?

Correlational research is the process of looking for relationships between variables that enables researches to predict changes in one variable on the basis of changes in another. A correlation is a relationship, either positive or negative between two or more variables. For example we can conduct a correlational research between student absences and their overall final grade. It is important tor remember that a correlation doesn't imply that one variable causes the other.
