Question 1

Quantitative Research Designs

Answer 1

• Descriptive Non-experimental
• Quasi-Experimental
• Experimental

Question 2

Classifying Quantitative Research Designs

Answer 2

• Is there an intervention?

If yes, the research design is either quasi-experimental or experimental
- Education, Treatment, Support

If no, the experiment is descriptive non-experimental
- Observational, Exploratory, Survey, Case-Control, Cohort, Correlational

Question 3

Classifying Experimental vs Quasi-Experimental

Answer 3

Is it a randomized control trial? (Gold Standard)

Yes - Experimental (Random sample, control group, intervention)

No - Descriptive Non-Experimental (no intervention) or Quasi-Experimental (no control group or randomization)

Question 4

Terms

Answer 4

Cross Sectional - Data was collected at ONE point in time

Longitudinal - Data was collected over a LONG period of time

Convenience Sampling - Sample was readily available to the researcher (hint that sample does not have random sample which means it will be Non-Experimental or Quasi-Experimental)
