What distinguishes an
experimental
research design from a
non-experimental
research design?

Experimental designs use multiple groups and quasi-experimental do not use multiple groups.

Experimental designs are designed by professional researchers and quasi-experimental designs are not.

Experimental designs have participant assignment to groups that is always done in a random way; Quasi-experimental designs have participant assignment to groups that is non-random.

Experimental designs always have manipulation of an independent variable and quasi-experimental designs never have maniupulation of an independent variable.
