-
Which design matches participants on key variables before placing them into separate conditions?
- Independent groups
- Single-blind design
- Repeated measures
- Matched pairs
-
What is the primary purpose of conducting a pilot study before a research investigation?
- Prove hypotheses
- Eliminate participant variables
- Establish significance
- Test procedures
-
In which experimental design are order effects most likely to distort the results?
- Repeated measures
- Matched pairs
- Independent groups
- Naturalistic observation
-
Which observational sampling technique counts every occurrence of a target behaviour whenever it happens?
- Random sampling
- Time sampling
- Event sampling
- Opportunity sampling
-
Which observational technique records target behaviour at specific predetermined time intervals?
- Stratified sampling
- Continuous sampling
- Event sampling
- Time sampling
-
A researcher counts the number of aggressive acts each child makes during a playground session. Which sampling method is used?
- Time sampling
- Matched pairs
- Event sampling
- Opportunity sampling
-
A researcher records the behaviour of each child every 10 seconds during a lesson. Which sampling method is used?
- Time sampling
- Volunteer sampling
- Random allocation
- Event sampling
-
Which technique controls order effects in a repeated measures experimental design?
- Double-blind procedure
- Random allocation
- Standardisation
- Counterbalancing
-
Which experimental design pairs participants on key characteristics before allocating one to each condition?
- Independent groups
- Repeated measures
- Matched pairs
- Single-case design
-
Which main limitation affects an independent groups experimental design?
- Participant variables
- Order effects
- Practice effects
- Demand characteristics
-
What primary action should a researcher take if a pilot study identifies unclear instructions?
- Increase sample size
- Change experimental design
- Revise the instructions
- Discard the study
-
Which design avoids order effects but requires more participants for the same amount of data?
- Matched pairs design
- Time sampling method
- Independent groups
- Repeated measures design
-
Why does a matched pairs design fail to eliminate all participant variables?
- Order effects occur
- Sample size decreases
- Unmatched differences remain
- Demand characteristics double
-
Which issue must be controlled when using a repeated measures design?
- High participant numbers
- Order effects
- Matching error
- Participant variables
-
Which experimental design requires the fewest participants to gather data for all conditions?

- Matched pairs
- Repeated measures
-
To ensure observational reliability, behavioural categories should be mutually exclusive and what?
- Subjectively interpreted
- Randomly assigned
- Clearly operationalised
- Broadly defined
-
How does conducting a pilot study improve the reliability of research?
- Identifies procedural flaws
- Guarantees significant results
- Eliminates participant attrition
- Increases statistical power
-
Which observational sampling method is best for recording rare target behaviours?
- Time sampling
- Stratified sampling
- Event sampling
- Systematic sampling
