Methodologies Flashcards
Experiments
An investigation which a hypothesis is scientifically tested. E.g. lab, field, natural.
Lab experiment
- Conducted in a lab.
- Can control extraneous variables.
- Controlled conditions.
Lab experiment - advantage & disadvantage
ADV = Can control extraneous variables.
DIS = Lacks ecological validity.
Field experiment
Conducted in a real world setting.
Field experiment - advantage & disadvantage
ADV = Some control, control over the IV.
DIS = Can’t control extraneous variables.
= Hard to repeat.
Natural experiment
An observational study conducted in a natural environment with no control over any variable.
Natural experiment - advantage & disadvantage
ADV = Ecological validity.
DIS = Can’t control any variables.
On-line research
Research carried out on the internet.
On-line research - advantage & disadvantage
ADV = Easy to get.
= Can get a wider / larger sample.
DIS = Social desirability bias.
Quasi-experiment
Participants can’t be randomly assigned to the IV. Requires a specific group of people.
Quasi-experiment - advantage & disadvantage
ADV = Designs can be strengthened with control groups.
DIS = Can’t rule out other factors.
Participant observation
Researcher does get involved.
Participant observation - advantage & disadvantage
ADV = Rich qualitative data.
DIS = Biassed. Risk of getting too involved.
Non participant observation
- Observing participants without actively participating.
- Not getting involved.
Non participant observation - advantage & disadvantage
ADV = No ethical issues if people know they’re being observed.
DIS = People act differently as they know they’re being observed. Demand characteristics.
Content analysis
Analysing methods used to identify key words and themes in qualitative data and convert them to quantitive data.
