Question

Quizplus · Accepted Answer

The biggest difference between correlational research designs and experimental research designs is the manipulation of variables. Experimental designs involve manipulating the independent variable in order to study its effect on the dependent variable, while correlational designs do not involve manipulation of variables. Instead, they observe and measure the naturally occurring relationships between variables.
