Document Summary

Research design: to see if you can do an experiment. If you have an iv: can do a lab, field or quasi experiment. If you have a subject variable: no: have to do a quasi experiment. If you need to be in the field: do a field or quasi-field experiment. All quasi means = as if": has some components of an experiment but not all. Refers to any uncontrolled factor that could alter your research / results: it co-varies with the levels of your iv. Ex: differences in comfort of lab across conditions. **and anything else that systematically varies with your level of iv example of a confound: Person is doing a reaction-time task on the computer (click as fast as possible when a cue comes up) 3 participants: 1 in a freezing cold lab, 1 in a hot lab, 1 in a comfortable setting.
