Q

Systematic Sampling

A

using predetermined system to select participants, same number has to be applied consistently unbiased, only truly unbiased if use random method to come up with number

27
Q

Stratified Sampling

A

subgroups are identified within a population and participants are obtained from each strata in proportion to their occurence in the population, selection using random, representative, time consuming

28
Q

Opportunity Sampling

A

select people who are most easily available, easy, biased

29
Q

Random Sampling

A

random technique, every member of target population has equal chance, may take time

30
Q

Confounding Variable

A

variables that arent IV but varies systematically with IV, can stop from establishing cause + effect

31
Q

Extraneous Variable

A

variables that change other than IV and are quite difficult to control, they make it difficult to detect a significant effect

32
Q

Pilot Study

A

small scale practice run of study to identify problems in design, method or analysis

33
Q

Standardisation

A

everything said must be scripted in advance to ensure fairness across conditions

34
Q

Matched Pairs Design

A

two equal groups used, one for each condition with the ps matched based on key variables

35
Q

Repeated Measures Design

A

only one group of ps is used for both conditions of the experiment

36
Q

Independent Groups Design

A

a separate group of ps for each condition of the experiment

37
Q

Experimental Design

A

how the ps are picked to stop other things interfering with results

38
Q

Null Hypothesis

A

states that there will be no difference between the 2 conditions in the experiment

39
Q

Non Directional Hypothesis

A

a hypothesis that states there would be a difference between the 2 conditions but wouldnt specify the direction it would go

40
Q

Directional Hypothesis

A

a hypothesis that indicates which direction the results will go

41
Q

Operationalism

A

strictly defining the variables into measurable factors

42
Q

Dependent Variable (DV)

A

what you measure in an experiment

43
Q

Independent Variable (IV)

A

what you change in an experiment

44
Q

Aim

A

starts with ‘to investigate/to establish’

45
Q

Cost Benefit Analysis

A

a balance between the best interests of the ps and the value of the research

46
Q

Controlled Observation

A

behaviour is observed under conditions where certain variables have been organised by the researcher

47
Q

Naturalistic Observation

A

it takes place in an everyday setting with no interference

48
Q

Overt Observation

A

the ps are aware they are being studied

49
Q

Covert Observation

A

it is kept secret from the ps that they are being studied

50
Q

Participant Observation

A

the observations are being made by someone who is also participating in the activity being observed

51
Q

Non-Participant Observation

A

the observer is separate from the people being observed
