What does historical research include
Accessing primary (i.e witnesses) or secondary (i.e literature) sources to document past events
What comes under philosophical research
Organising existing evidence into a comprehensive theoretical model
What are the types of observational research
Case study
Survey
What is a longitudinal design
Involves examining the same groups’ perf at different time points.
Participant drop-out rate is often a problem.

Correlation
Linear regression
Multiple regression
What is observational research useful for?
Establishing relationships between variables
Negative to observational research
Difficult to infer causality
- You know there’s a relationship between the 2 but you don’t know which causes which

Interval
Ratio
Pre-experimental design
1 group - no control group
No random assignment to groups
Process of pre-experimental design
Pre-test measurement
Treatment
Post-test measurement
Quasi-experimental design
What are the types
Static group comparison
Causal comparison
Is there random assignment in the quasi-experimental design static group comparison
NO
Quasi-experimental design
Static group comparison
- Treatment group is compared to control group
Quasi experimental design
Causal comparison
Similar to static group comparison but the treatment is not under the control of the experimenter
How do you test the quality of a study research design?
Studys conclusion validity
What comes under an effective research design
Maximise systematic variance
Minimise error variance
Identify + control for confounding variables
What is a confounding variable
A variable producing underside variation in the studys dependent variable
