Quasi experimental designs can be:
A. Non Equivalent groups design

B. Non-Cohort design

C. Equivalent groups design

D. Cohort design

E. True experiment design

Correct option is C

Quasi-experimental designs are research designs that attempt to establish cause-and-effect relationships, but without the random assignment of participants to groups. The correct answers are:
· A. Non Equivalent groups design: This is a common type of quasi-experimental design where groups are not randomly assigned but are compared. The groups may differ in some respects that could influence the outcome, which makes it a "quasi" rather than a true experiment.
· D. Cohort design: This design involves studying a group of individuals over time, observing their experiences or exposures and how these relate to outcomes. While it's often used in observational studies, it’s considered a form of quasi-experiment because there is no random assignment.
Information Booster
A. Non Equivalent groups design In non-equivalent groups designs, participants are assigned to different groups without randomization. As a result, the groups might differ in important ways that could affect the study’s outcomes. Researchers using this design must be cautious of biases, but it’s still useful for exploring causal relationships in real-world settings where random assignment is not feasible. This type of design can often be used in educational or clinical settings.
D. Cohort design Cohort designs typically follow a group of individuals who share a common characteristic (e.g., age, experience, or exposure) over time. These designs are used to track changes in these individuals and see how they relate to certain outcomes. Like non-equivalent group designs, cohort designs are considered quasi-experimental because they don’t involve random assignment. They provide valuable insights into causal links, especially in fields like public health.
Additional Knowledge
B. Non-Cohort design Non-cohort designs are not typically associated with quasi-experimental designs. Cohorts refer to specific groups being studied, so "non-cohort" does not fit within the category of quasi-experiments.
C. Equivalent groups design Equivalent groups are more typical of true experimental designs, where participants are randomly assigned to groups, ensuring that the groups are similar in all respects before the intervention. This is not a characteristic of quasi-experimental designs, which usually involve non-randomized groups.
E. True experiment design True experimental designs are those where participants are randomly assigned to groups and conditions. This randomization is key to eliminating biases and ensuring equivalent groups, making them different from quasi-experimental designs, which do not have random assignment
