Q

Correlational Analysis

A

A mathematical technique where the researcher looks to see whether scores for two covariables are related

39
Q

Counterbalancing

A

A way of trying to control for order effects in a repeated measures design, e.g. half the participants do condition A followed by B and the other half do B followed by A

40
Q

Critical Value

A

The value that a test statistic must reach in order for the hypothesis to be accepted.

41
Q

Debriefing

A

After completing the research, the true aim is revealed to the participant. Aim of debriefing = to return the person to the state s/he was in before they took part.

42
Q

Demand Characteristics

A

Occur when participants try to make sense of the research situation they are in and try to guess the purpose of the research or try to present themselves in a good way.

43
Q

Dependent Variable

A

The variable that is measured to tell you the outcome.

44
Q

Descriptive Statistics

A

Analysis of data that helps describe, show or summarise data in a meaningful way

45
Q

Dispersion Measure

A

A dispersion measure shows how a set of data is spread out, examples are the range and the standard deviation

46
Q

Double Blind Control

A

Participants are not told the true purpose of the research and the experimenter is also blind to at least some aspects of the research design.

47
Q

Ethical Guidelines

A

These are provided by the BPS - they are the ‘rules’ by which all psychologists should operate, including those carrying out research.

48
Q

Ethical Issues

A

There are 3 main ethical issues that occur in psychological research – deception, lack of informed consent and lack of protection of participants.

49
Q

Evaluation Apprehension

A

Participants’ behaviour is distorted as they fear being judged by observers

50
Q

Event Sampling

A

A target behaviour is identified and the observer records it every time it occurs

51
Q

Extraneous Variable

A

Variables that if not controlled may affect the DV and provide a false impression than an IV has produced changes when it hasn’t.

52
Q

Histogram

A

A graph that is used for continuous data (e.g. test scores). There should be no space between the bars, because the data is continuous.

53
Q

Independent Variable

A

The variable that the experimenter manipulates (changes).

54
Q

Inferential Statistics

A

Inferential statistics are ways of analysing data using statistical tests that allow the researcher to make conclusions about whether a hypothesis was supported by the results.

55
Q

Informed Consent

A

Psychologists should ensure that all participants are helped to understand fully all aspects of the research before they agree (give consent) to take part

56
Q

Interval Level Data

A

Data measured in fixed units with equal distance between points on the scale

57
Q

Investigator Effects

A

These result from the effects of a researcher’s behaviour and characteristics on an investigation.

58
Q

Measures of Central Tendency

A

A measurement of data that indicates where the middle of the information lies e.g. mean, median or mode

59
Q

Meta Analysis

A

A technique where rather than conducting new research with participants, the researchers examine the results of several studies that have already been conducted

60
Q

Nominal Level Data

A

Frequency count data that consists of the number of participants falling into categories. (e.g. 7 people passed their driving test first time, 6 didn’t).

61
Q

Observer Bias

A

Occurs when the observers know the aims of the study study or the hypotheses and allow this knowledge to influence their observations

62
Q

Open Questions

A

Questions where there is no fixed response and participants can give any answer they like. They generate qualitative data.

63
Q

Operationalising Variables

A

This means clearly describing the variables (IV and DV) in terms of how they will be manipulated (IV) or measured (DV).

64
Q

Opportunity Sample

A

Participants are chosen because they are easily available
Easy
Not representative

65
Q

Order Effects

A

Order effects can occur in a repeated measures design and refers to how the positioning of tasks influences the outcome e.g. practice effect or boredom effect on second task

66
Q

Ordinal Level Data

A

Data that is capable of being out into rank order (e.g. places in a beauty contest, or ratings for attractiveness).

67
Q

Presumptive Consent

A

Asking a group of people from the same target population as the sample whether they would agree to take part in such a study, if yes then presume the sample would

68
Q

Primary Data

A

Information that the researcher has collected him/herself for a specific purpose e.g. data from an experiment or observation

69
Q

Prior General Consent

A

Information that the researcher has collected him/herself for a specific purpose e.g. data from an experiment or observation

70
Q

Protection from Harm

A

Participants should be protected from physical or mental health, including stress - risk of harm must be no greater than that to which they are exposed in everyday life

71
Q

Random Sampling

A

Everyone in the target population has an equal chance of being selected
Less bias, more representative
Can’t be truly random

72
Q

Randomisation

A

Refers to the practice of using chance methods (e.g. flipping a coin’ to allocate participants to the conditions of an investigation

73
Q

Representative Sample

A

A sample that closely matched the target population as a whole in terms of key variables and characteristics

74
Q

Retrospective Consent

A

Once the true nature of the research has been revealed, participants should be given the right to withdraw their data if they are not happy.

75
Q

Scattergram

A

Used to plot correlations where each pair of values is plotted against each other to see if there is a relationship between them.

76
Q

Secondary Data

A

Information that someone else has collected e.g. the work of other psychologists or government statistics

77
Q

Semi-structured Interview

A

Interview that has some pre-determined questions, but the interviewer can develop others in response to answers given by the participant

78
Q

Sign Test

A

A statistical test used to analyse the direction of differences of scores between the same or matched pairs of subjects under two experimental conditions

79
Q

Significance

A

If the result of a statistical test is significant it is highly unlikely to have occurred by chance

80
Q

Single-blind Control

A

Participants are not told the true purpose of the research

81
Q

Social Desirability Bias

A

Participants’ behaviour is distorted as they modify this in order to be seen in a positive light.

82
Q

Standardised Instructions

A

The instructions given to each participant are kept identical – to help prevent experimenter bias.

83
Q

Standardised Procedures

A

In every step of the research all the participants are treated in exactly the same way and so all have the same experience.

84
Q

Stratified Sample

A

Groups of participants are selected in proportion to their frequency in the target population
Less bias, more representative
Difficult to define strata

85
Q

Structured Interview

A

Interview where the questions are fixed and the interviewer reads them out and records the responses

86
Q

Structured Observation

A

An observation study using predetermined coding scheme to record the participants’ behaviour

87
Q

Systematic Sample

A

Every nth person in a list of the target population is selected
Less bias, more representative
A biased list will make biased results

88
Q

Time Sampling

A

A way of sampling the behaviour that is being observed by recording what happens in a series of fixed time intervals.

89
Q

Type I error

A

Is a false positive. It is where you accept the alternative/experimental hypothesis when it is false

90
Q

Type II Error

A

Is a false negative. It is where you accept the null hypothesis when it is false

91
Q

Unstructured Interview

A

Also know as a clinical interview, there are no fixed questions just general aims and it is more like a conversation

92
Q

Unstructured Observation

A

Observation where there is no checklist so every behaviour seen is written down in an much detail as possible

93
Q

Volunteer Sample

A

Participants put themselves forward to take part in research, often by answering an advertisement
Less likely to withdraw, easy
Not representative, volunteer bias
