Research methods in psychology worksheet with answers

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

1. ANominal
2. BInterval
3. COrdinal
4. DRatio

The mode of a data set is:

1. AThe most frequently occurring value
2. BThe middle value when scores are ordered
3. CThe arithmetic average of all values
4. DThe difference between highest and lowest values

Test-retest reliability is assessed by:

1. AGiving the same test to the same people on two occasions and correlating the scores
2. BChecking whether the items appear, on the surface, to measure what the test claims to
3. CComparing a new test with an established one
4. DHaving two observers code the same behaviour

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

1. AAn order effect
2. BA floor effect
3. CA practice effect
4. DA ceiling effect

In a perfectly normal distribution:

1. AThe mean, median and mode are equal
2. BMost scores lie in the tails
3. CThe mean is always larger than the median
4. DThe mode is the lowest score

In a field experiment, the researcher:

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

Why do many researchers argue that p-values should be reported together with effect sizes and confidence intervals?

1. AP-values show the probability the hypothesis is true
2. BConfidence intervals are only needed in qualitative research
3. CEffect sizes make sample size irrelevant to significance
4. DA p-value does not show how large or precise the effect is

After analysing the data, a researcher writes the introduction as if an unexpected finding had been predicted all along. This is called:

1. ADebriefing
2. BHARKing (hypothesising after the results are known)
3. CCounterbalancing
4. DOperationalisation
