- experimental design
- experiments are usually about 2 conditions
- 1) might be to have no caffine given to participants (control group) 2)participants are given a aprkling sugar drink (experimental group)
- the iv is the amount of caffine consumed, while the dv is the outcomeof the degree of talkativeness
- 1) might be to have no caffine given to participants (control group) 2)participants are given a aprkling sugar drink (experimental group)
- counter balancing
- here half of the sample take part in condition 1 and half in condition 2 then swap conditions
- matched pairs
- here there is an independent design but the 2 samples are matched as much possible
- evaluation
- as participants only take part in a singe condition so order effects and demand characteristics are less of a problem
- there is some attempt to reduce participant variable but participants can never be matched exactly
- matching may be time consuming and expensive particularly if a pre-test is required
- so this is less economical than others

- experiments are usually about 2 conditions
