True experiments, in which all the important factors that might affect the phenomena of interest are completely controlled, are the preferred design. Often, however, it is not possible or practical to control all the key factors, so it becomes necessary to implement a quasi-experimental research ...
Between Subjects Nonexperimental and Quasi-experimental designs: Nonequivalent Group Designs (p. 285) ... A non-equivalent group design isone where the assignment of participants to groups is not controlled by the investigator. When group assignment is not controlled there is a significant threat t...
What is the invisible gorilla experiment? What was the 'obvious' part in the bridge experiment? What effect does a placebo have in an experiment? What are a few examples of conditions for a quasi-experimental design? What was the Stanford Prison Experiment?
Countless quasi-experimental topics focus on a person’s environment or social setting. For example, a sociologist may research two boys of the same age who live in the same poor neighborhood, attend the same schools and have access to the same opportunities. If one boy is on his way to H...
Intergovernmental Transfers and Elementary Education: Quasi-Experimental Evidence from Brazil Whether providing additional resources to local communities leads to improved public services and better outcomes more generally, given existing management capacity and incentive and accountability structures, is an unreso...
What is an example of group conformity? Explain how reliability is related to validity, and/or vice versa. What are some modern examples of doublethink? What is an example of counterfactual thinking? What are a few examples of conditions for a quasi-experimental design?
Random assignment is a hallmark of a “true experiment”—it differentiates true experiments from quasi-experiments. Example: Random assignmentTo divide your sample into groups, you assign a unique number to each participant. You use a computer program to randomly place each number into either a...
Quasi-experimental design. This study used a 2 (pricing: PWYW vs. fixed) × 2 (customer fatigue: high vs. low) design. We alternated the pricing strategy in 30-minute blocks, such that PWYW pricing was in place for 30 min, followed by fixed price for 30 min, and so on. Participants...
3. Develop a Solid Research Design Choose an appropriate research design that aligns with your objectives, whetherexperimental, quasi-experimental, or correlational. You also need to pay attention to thesample size and sampling techniqueso that they accurately represent the target population. ...
One of these investigated the effectiveness of a cross-disciplinary approach (including mathematics, social studies, science, and English language arts) to promote data literacy compared to a non-disciplinary approach in a quasi-experimental design with independent groups (Vahey et al., 2012). ...
