Study Notes
Research Design Types
- A Factorial Design involves the manipulation of two or more independent variables simultaneously.
- A Quasi-Experimental Design lacks random assignment of participants to groups.
- A Randomized Control Trial (RCT) involves random assignment of participants to different conditions or groups.
- A Quasi-Experimental Design may use pre-existing groups or natural variations.
- A Factorial Design allows examination of main effects and interaction effects.
- A Laboratory Experiment involves control over extraneous variables.
- An example of a Quasi-Experimental Design is investigating the impact of a teaching intervention in existing classrooms without randomly assigning students to the intervention.
- The key characteristic that distinguishes a Randomized Control Trial (RCT) from other research designs is the random assignment of participants to groups.
- A Descriptive Study aims to describe the characteristics of a phenomenon without manipulating variables.
- The main focus of Correlational Studies is to identify relationships between variables.
- In a Retrospective Study, data collection occurs after the events or outcomes have already occurred.
- What distinguishes a Prospective Study from a Retrospective Study is that data collection occurs before the events or outcomes have occurred.
- The common statistical measure used in Correlational Studies is correlation coefficient.
- In a Randomized Control Trial (RCT), the control group receives a placebo or no treatment.
- The emphasis of Non-experimental Research Designs such as Descriptive Studies is on describing the characteristics of a phenomenon rather than explaining it.
