3.9 Quasi-experimental designs | Quantitative methods | Research Designs | UvA

This video explains what quasi-experimental designs are. Sometimes researcher are unable to do a random assignment of participants, or sometimes there is no manipulation. In this case researchers use a quasi-experimental design. Different quasi-experimental designs discussed in this video are: static group comparison, pre/posttest non-equivalent control group, interrupted time-series and replicated interrupted time-series.

Very helpful and quite advanced but once it clicks it really helps. You can tell the lecturer has incredibly in-depth knowledge of study methodology.

v complicated, didn't understand much

Is a dose size effect often included in quasi-experiments? For example, one group would play a violent game for 5 minutes, while another group would play a violent game for 2 hours. I've heard of these effects being used when looking for causal evidence in non-experimental data, but I'm not sure if I've heard of them being deliberately designed into quasi-experiments.

May I ask, what statistical test should be used when a using the Pretest-Posttest non-equivalent control group design?

this was really helpful thank You very much :D

[mohammadyamini]

thanks, your lecture is very good and I wish to continue that.

Very helpful explanation. Tq for sharing.

So hard to follow... Probably just me though. Fuck stats and research methods lol.

complicated to some extent. I gained a little.
