- Scattergraph - a way of displaying data collected from a correlation.
- Perfect negative - the scattergraph shows a negative correlation.
- Perfect positive - the scattergraph shows positive correlation.
- No correlation - the scattergraph shows no pattern.
- Co-variables - the two things that are being correlated.
- Null hypothesis - a hypothesis predicting no significant difference.
- Correlational hypothesis - shows the predicted results (positive, negative or no correlation).
- Scattergraph - a way of displaying data collected from a correlation.
- Self-report
- Closed question - a question with a yes/no answer.
- Open question - usually starts with who, what, where, when, why, how?
- Fixed choice question - a question with a set of pre-set answers.

- Unstructured interview - participants can discuss topics freely.
- Rating scales - participants rate their agreement on an explained scale.
- Experiment
- Field - an experiment carried out in a natural setting, IV is manipulated.
- Laboratory - an experiment carried out with extremely high control, IV is manipulated and method is standardised.
- Natural (Quasi) - an experiment carried out in a natural setting, IV is not manipulated.
- Extraneous variables - outside variables that may affect the results.
- Cause & effect - Saying that the IV caused the DV to give certain results.
- Experimental design
- Matched participants - similar to independent measures, groups are allocated by measuring a certain variable and matching pairs of participants on said variable.
- Repeated measures - participants partake in every condition.
- Independent measures - participants are only allocated to one condition.
- Observation
- Tally chart
- Participant observation - observation carried out by a person in the group being observed.
- Disclosed/Covert - participants are aware that they're being observed.
- Behaviour checklist - a list of behaviours to be observed.
- Event sampling - noting every time a behaviour is observed.
- Time sampling - sampling for one or more short periods of time.
- Undiclosed/Overt - participants are aware that they're being observed.
- Structured observation - observation with a clearly defined system for recording behaviour.
- Correlation
