- 1 tailed: gives effect and direction
- 2 tailed: gives effect but not direction
- Population, Sample & Sampling Tehniques
- Target population: who the researcher is interested in studying
- Sample: actual group of participants in research
- Sampling techniques
- Snowball: participants bring fam & friends
- STR: cheap & easy
- WEA: bias, no number guarentee
- Self-select: people volunteer
- STR: automatic consent
- WEA: bias to personality
- Random: each has equal chance of being chosen
- STR: best chance of unbias
- WEA: participant may not want to take part
- Opportunity: using most readily available
- STR: quick & conveniant
- WEA: may be bias
- Snowball: participants bring fam & friends
- Experimental Designs
- Repeated: same people in all condition
- STR: no participant variables
- Weakness: order effects & demand characteristics
- Independent: dif people in all conditions
- STR: no order effects
- WEA: participant variables
- Matched Pairs: dif people in all conditions but have similarities
- STR: reduced participant variables & no order effects
- WEA: takes time & hard to match
- Repeated: same people in all condition
- Variables
- Independent: the one factor that is changed
- Dependent: the factor being measured
- Extraneous variables need to be controlled or affect results
- Participant variables: personality affects behaviour
- Enviromental variables: surrounding enviro & controls affect behaviour
- Order Effects: repetition with same participants, they may improve second time
- Demand Characteristic: change in behaviour if study purpose is known
