What distinguishes correlational studies from correlational analysis?

What will be an ideal response?

Correlational studies are those whose methodology involves variables that are not manipulated; they are measured as they exist. Such studies can help detect relationships between variables but not cause. Correlational analysis involves different types of statistical approaches. The approaches are correlational, but if the methodology is such that it can legitimately lead to causal analysis, the correlational approach does not mean that the researcher can't invoke causal statements.
