Study Notes
Research Design Types
- One Shot Case Study: No control group, no random assignment, only posttest
- One Group Pretest Posttest: No control group, no random assignment, pre- and posttest
- Interrupted Time-Series: No control group, no random assignment, many measurements
- Equivalent Time-Series: No control group, no random assignment, many measurements and multiple interventions
- Static Group Comparison: Experimental group and control group, no random assignment, no pretest or follow-up measurement
- Two Groups Posttest Only: Experimental and control group, random assignment, no pre-test or follow-up
- Classic Experiment: Experimental and control group, random assignment, pre- and posttest, sometimes follow-up measurements
- Solomon Four Group: Experimental and control group, random assignment, pretest and posttest vs. posttest only
- Factorial: Experimental and control group for each level of 2nd factor, random assignment, at least posttest
