Question

How do quasi-experiments differ from true experiments?

1) Quasi-experiments lack random assignment to control and experimental groups.
2) Quasi-experiments have random assignment to control and experimental groups.
3) Quasi-experiments have more participants than true experiments.
4) Quasi-experiments have fewer participants than true experiments.

Answer 1

Quasi-experiments differ from true experiments by lacking random assignment to control and experimental groups, making it more difficult to establish cause-and-effect relationships. Quasi-experiments may still have comparable group sizes to true experiments depending on the research design.

Step-by-step explanation:

Quasi-experiments differ from true experiments in that they lack random assignment to control and experimental groups. In a true experiment, participants are randomly assigned to groups, while in a quasi-experiment, participants are not randomly assigned. This lack of random assignment makes it more difficult to establish a cause-and-effect relationship between the independent and dependent variables. Quasi-experiments may still have comparable group sizes to true experiments, depending on the research design and availability of participants.
