Thanks a lot for your lovely lecture notes. If the comparison group goes to intervention as the second group, why do we call the design non-equivalent control group ? Non-equivalent comparison groups are more appropriate or not ?
Compare the difference ( changes within groups) between both groups and be careful since this is considering internal validity threatening, and the best way to avoid it is to do time series design.

You explained it better than my professor. Thank you! Would you please share the slides?
Can you please give 2 example of quantitative research title that is quasi-experimental design
How are we going to interpret data if the pretest and posttest is different?
