Dependent Variables: These are the outcomes that are measured in response to changes in the independent variables. 1 PSELECT4 Experimental Method / REVIEWER/ Midterms Padayon! Types of Experimental Designs Non-Experimental Approach True Experimental Design Why do we use non-experimental approaches? This design relies on random assignment and manipulation of variables, allowing for strong Internal Validity External Validity conclusions about causality.

Useful in real-world settings Exp: non-experimental methods may where random assignment is struggle with internal validity because not feasible. they don’t control all variables, but they can often have strong external validity because they observe naturally occurring Pre-Experimental Design conditions.
