that is not controlled, which could
affect the results of a study.
3 of 49

Confounding variable: an
extraneous variable that affects
the results of the study so that
the effect of the IV is not truly

4 of 49
Define operationalisation
Operationalisation: making
the variables in an investigation
detailed and specific.
5 of 49

Order effects: when participants
improve or worsen in the second
condition because they have

response to the perceived aims of
the investigation.

Investigator effect: when a
researcher unintentionally gives
clues to participants, altering their
behaviour.

Participant variables: extraneous
variables specific to the participants
of an investigation, for example
their mood, ability or personality.

Standardised procedure: where
the procedure of a study is the same
across all conditions.
10 of 49
Define counterbalancing
Counterbalancing: where half of the participant
group experience condition A then condition B,
while the other half experience condition B then
condition A.
11 of 49
Define Randomisation
Randomisation: when participants are randomly
assigned to condition A or B as their first or second
test condition.

Null hypothesis: a prediction that the results will
fail to show any difference (or relationship) that is
consistent or systematic.
15 of 49
Define Alternative hypothesis
Alternative (experimental) hypothesis: a
prediction of the outcome of a study based on what

Define Directional hypothesis
Directional hypothesis: a hypothesis that predicts
the direction the results will go in.
17 of 49

Sample: a selection of the target population that is
directly studied in an investigation.
21 of 49
Define Generalisability
Generalisability: the extent to which the results of
a study represent the whole population, not just the sample used.

Sampling method: a technique used to gather a
representative group of people as a sample from the
target population.
23 of 49

gather a random sample of participants from the
target population.
24 of 49

Sample error: when a sample
differs in qualities from the
target population it intends to
represent.

a technique that asks for
participants by placing an advert
for volunteers.
27 of 49
Define Biased sample
Biased sample: when the
sample recruited is made up
of a particular type of person,
which may not reflect the target
population.
28 of 49

Opportunity sampling
technique: a technique that
recruits participants who are
readily available at the time.
29 of 49

Research design: how What you will learn participants are allocated to the
conditions of a study.
30 of 49
Define experimental design
Experimental design: the name
given to research design when
used in an experiment.
31 of 49
Define independent measures design
Independent measures design:
participants are split into groups,
with each group tested in only
one condition of a study.
32 of 49
Define repeated measures
Repeated measures design: the
same participants are used in all
conditions of a study.
33 of 49
Define Matched pairs design
Matched pairs design: different
participants are used in each
condition of the study, but
are matched for likeness on
important characteristics.
34 of 49
Define Reliability
Reliability: the consistency of an outcome or result
of an investigation (a measure).
35 of 49
Define validity
Validity: whether the test measures what was
intended.
36 of 49
Define interal validity
Internal validity: whether the measures used in a
test genuinely test what they were designed to test.
37 of 49
Define External validity
External validity: whether the findings are
generalisable to the target population.
38 of 49
Define Qualitative methods
Qualitative methods: ways of
conducting research that find
out new information rather
than testing a prediction; often
resulting in gathering qualitative
data.
39 of 49

researcher interprets the
outcome of a study according to
their own view (subjective).
