- Non-directional hypothesis = doesn't state the direction
- Variables
- Definition: any 'thing' that can vary or change within an investigation
- Independent variable = some aspects of the experimental situation that is manipulated by the researcher - or changes naturally -so the effect on the DV can be measured
