Qualitative examples
Narrative
* Ethnographic
* Participant observation
* Focus groups
* Document analysis
Many more types in qualitative research
Note* not all qualitative research is observational
is a placebo an iv
no
Pre-experimenta
Pre-experimental groups the IV is manipulated for everyone.
Quasi-experimental (non-random control) with or without
Crossover design
Quasi-experimental studies everyone is their own “control”
Subject group is relatively small (most of the time)
or control is not chosen randomly (ie self selected)
Most bang for your buck can be used in conditions where the
measure is difficult there are problems when you don’t have
randomization or a “true” control
And…
Qualitative subsamples of experimental designs.
Single-Case Experimental Design
2.Focus Group Study
3.Ethnographic Study
4.Phenomenological Study
5.Grounded Theory Study
6.Case Study

which studies can you add retro to
case control and cohort
cohort study
select a group of peoople based on particular exposure follow them over time to asses the develmonte of an out come
case control
select participants with and without a specific out come compare gropus to identfy assosiated risk factors

Document analysis
Document analysis is a research method where documents are systematically reviewed and evaluated to extract meaningful information, patterns, and insights.
.Single-Case Experimental Design
A single-case experimental design is a research method where the behavior of a single subject is measured repeatedly before, during, and after an intervention to assess its effects.
.Grounded Theory Study
A grounded theory study is a research method that involves generating a theory based on data collected from participants, focusing on discovering patterns and relationships through an iterative process of data collection and analysis.
