Experimental vs Non-Experimental Research Methods

• Non-Experimental Research: Does not require experiment

Statistical Significance vs Effect Size vs Correlation vs Causation

• Statistical Significance: Unlikelihood of chance

• Effect Size: Strength of a relationship

• Correlation: Relation between 2 variables (correlation ≠ causation)

• Causation: 1 thing causes another

How is causation determined?

• Cause comes before effect

• Variable can be manipulated to change something (1 directional)

• Confounding variables ruled out
