Experimental Designs

Experimental design is....

• How participants are selected

• How participants are allocated to conditions

• How EV's are controlled

• How we operationalise the IV and DV

Odd one out

• Indepedent

• Matched

• Quasi

• Repeated

True or false: Independent measures involved allocating to different conditions

• True

• False

True or false: Repeated measures is using the same participants in all conditions

• True

• False

True of false: Matched pairs is efficient and saves time

• True

• False

Repeated measures is high in..... (SELECT TWO)

• Order effects

• Demand Characteristics

• Investigator effects

• Participant Variability

Independent measures can be improved by.......

• Counterbalancing

• Random allocation

• Deceiving participants

• Standardising procedures

Order effects are.....

• When the participant guesses the aim

• When participants have differing characteristics in different conditions

• When participants get better or worse in the second condition

• When participants don't wish to continue

Order effects can be minimised by....

• Counter ordering

• Counter balancing

• Counter neutralising

Independent measures is low in (select TWO)

• Demand Characteristics

• Order effects

• Participant variability

• Efficiency
