Research methods in psychology worksheet with answers

In a matched pairs design:

1. AOnly twins can take part
2. BParticipants are paired on relevant characteristics and one of each pair goes into each condition
3. CParticipants are randomly allocated with no matching
4. DThe same participants take part in all conditions

A small-scale trial run of a study before the main research is called:

1. AA pilot study
2. BA field experiment
3. CA replication
4. DA meta-analysis

Ranking runners as first, second and third produces which level of data?

1. ANominal
2. BInterval
3. CRatio
4. DOrdinal

In a field experiment, the researcher:

1. AManipulates the IV in a real-world setting
2. BAnalyses data collected by others
3. COnly observes without manipulating anything
4. DManipulates the IV in a laboratory

A test is so easy that almost all participants score near the maximum. This is called:

1. AA ceiling effect
2. BAn order effect
3. CA floor effect
4. DA practice effect

A researcher studies the effect of gender on memory scores. Why is this a quasi-experiment rather than a true experiment?

1. AThe study takes place in a laboratory
2. BThe IV is a pre-existing characteristic, so participants cannot be randomly allocated to it
3. CThe DV is not measured
4. DThere are only two conditions, and a true experiment needs at least three levels of the IV

Effect size measures such as Cohen's d are reported because they:

1. AReplace the need for any hypothesis
2. BShow how large an effect is, regardless of sample size
3. CShow whether the result is statistically significant at the chosen alpha level
4. DTell how many participants dropped out

A memory study uses a repeated measures design where everyone learns list A then list B. Recall is better for list B. What is the most likely flaw?

1. AThe use of an ordinal level of measurement
2. BToo large a sample size
3. COrder effects such as practice, because conditions were not counterbalanced
4. DIndividual differences between the groups
