  1. KINDS OF EXPERIMENT • Laboratory experiments (controlled, artificial conditions): • Pretest-post-test control and experimental group • Two control groups and one experimental group pretest-post-test • Post-test control and experimental group • Post-test two experimental groups • Pretest-post-test two treatment • Matched pairs; • Factorial design; • Parametric design; • Repeated measures design; • Field experiments (controlled conditions in the ‘real world’): • one-group pretest-post-test; • non-equivalent control group design; • time series • Natural experiments (no control over real world conditions)
