Bias

A

This limits the extent to which a sample can be generalised to the whole population as some groups might become over or under represented.

Q

Matched Pairs Design (MPD)

A

Pairs of participants are first matched on some variables that may affect the DV. Then one member of each group is assigned to condition A and the other to condition B.

Q

Random allocation

A

An attempt to control for participant variables in an IGD which ensure that each participant has the same chance of being in one condition as any other.

28
Q

Order effect

A

A confounding variable that occurs in RMD due to the order in which participants take part in each condition

29
Q

Counterbalancing

A

An attempt to control the effect of order effects in RMD: half of the participants experience conditions in one order (A to B) and the other in the opposite (B to A)

30
Q

Laboratory Experiment

A

An experiment takes place in a controlled environment within which the researcher manipulates the IV and records the effect on the DV, whilst maintaining strict control of extraneous variables

31
Q

Field experiment

A

An experiment that takes place in a natural setting within which the researcher manipulates the IV and records it’s effect on the DV

32
Q

Natural experiment

A

An experiment where the change in the IV is not brought about by the researcher but would’ve occurred even if the researcher had not been there. The researcher records the effect of the DV

33
Q

Quasi-experiment

A

A study that is almost an experiment but the IV has not been determined by anyone. The “variables” simply exist, such as being old or young.

34
Q

Pilot Study

A

A small scale version of the real investigation, done before the official one in order to check procedures, materials, measuring devices, etc to see if they work properly. This allows changes to be made if issues occur. Findings are IRRELEVANT

35
Q

Naturalistic observation

A

Watching behaviour in the setting in normally occurs in

36
Q

Controlled observation

A

Watching and recording behaviour within a structured environment

37
Q

Covert observation

A

Participants’ behaviour watched and recorded WITHOUT their knowledge

38
Q

Overt observation

A

Participants’ behaviour watched and recorded WITH their knowledge and consent

39
Q

Participant observation

A

When the researcher becomes a part of the group they are observing

40
Q

Non-Participant observation

A

the researcher remains outside of the group whose behaviour is being recorded

41
Q

Unstructured observation

A

every instance of a behaviour is recorded in as much detail as possible. Useful when target behaviour doesn’t occur often

42
Q

Structured observation

A

researcher uses various systems to organise observations, such as a sampling technique and behavioural analysis

43
Q

Target behaviour

A

behaviours which are the main focus of an investigation

44
Q

Behavioural categories

A

When a target behaviour is broken up into components that are observable and measurable

45
Q

Behaviour checklist

A

a checklist of behaviour(s) to be observed in individual components. Each component should should be an observable behaviour which is measurable

46
Q

Continuous recording

A

making a note of everything without pause

47
Q

Event sampling

A

When researcher records the number of times a particular behaviour or event occurs in a target individual group

48
Q

Time sampling

A

When a researcher records behaviour within a pre-determined time frame

49
Q

Inter-observer reliability

A

the extent to which there is an agreement between multiple observers involved in an observation of behaviour. This is measured by correlating the observations of two or more observers. If the correlation is +0.8 then there is a high observer reliability.

50
Q

Quantitative data

A

data that can be counted, usually numer9ical

51
Q

Qualitative data

A

data that is expressed in words and non-numerical form

52
Q

Observer bias

A

When observer’s expectations affect what they see or hear. This reduces validity

53
Q

Self report technique

A

any method in which a person is asked to state and explain their own feelings, opinions or experiences related to a given topic

54
Q

Questionnaire

A

a set of written questions used to asses a person’s feelings or experiences. Participants write their own response to the question. Can be used as part of the experiment to assess the DV

55
Q

Interview

A

A ‘live’ encounter where the interviewer asks a set of questions to asses the interviewee’s thoughts/experiences.

56
Q

Structured interview

A

questions are decided in advance. A questionnaire delivered in person

57
Q

Unstructured interview

A

starts with general questions with some general aims but the interviewee’s answers guide the subsequent questions. Interaction is free free flowing and interviewee is encouraged to expand their answers

58
Q

Semi-structured interview

A

a combination of a structured and an unstructured one. Some predetermined questions and aims but the interaction is generally free flowing

59
Q

Interviewer schedule

A

a set of pre set questions for the interviewer to use

60
Q

Interviewer bias

A

bias that arises due to the interviewers behaviours, i.e. how they respond to the interviewee or the topics they are interested in

61
Q

Group interview

A

more than one participant interviewed at one time

62
Q

Case studies

A

they are in-depth investigation, description and analysis of a single individual, group or institution.

63
Q

Content analysis

A

technique for analysing qualitative data of various kind. Data can be placed into categories and counted (quantitative) or analysed in themes (qualitative)

64
Q

Coding

A

a stage of content analysis in which the data is viewed and each instance of chosen categories is recorded in a tally chart (counted up)

65
Q

Thematic analysis

A

inductive and qualitative approach that involves identifying implicit or explicit ideas within the data. The data is then a=organised according to these themes
