- Lab Experiments
- Independent Measures Design
- Pps are placed in separate groups. Each group does one level of I.V. Compare D.V of groups
- Pps can't guess aim
- No order effects
- Researcher cannot control pps variables
- Randomly allocate pps to distribute pps variables
- Needs more pps for the same amount of data
- Repeated Measures Design
- Pps receive all levels of I.V. Compare D.V of pps on the tests
- No individual pps differences
- Less pps needed
- Order effects
- Counterbalancing
- Pps may guess the aim on 2nd test
- My use 2 diff tests
- Matched Pairs Design
- Pps matched on similar characteristics relevant to performance of D.V. Then same as Independent Measures design
- Minimised individual differences
- Very time consuming
- Hard to match people
- Conduct a pilot study to consider key variables
- Need lots of pps
- Independent Measures Design
