Q

What is quantitative data? What type of question usually generates this?

A

Numerical data.
Closed questions usually generate this data as you can count up the number of responses.

48
Q

What is qualitative data? What type of data usually generates this?

A

Non-numerical data.
Open questions usually generate this as there are lots of words/ pictures to analyse.

49
Q

Give a STRENGTH of Qualitative/ open questions:

A

More detailed answers mean more detailed conclusions can be made.

50
Q

Give a WEAKNESS of Qualitative/ open questions:

A

Time-consuming, and may receive answers from confused participants.

51
Q

Give a STRENGTH of Quantitative/ closed questions:

A

Easier and faster to collect data

52
Q

Give a WEAKNESS of Quantitative/ closed questions:

A

Lacks any background information

53
Q

Give a STRENGTH of Questionnaires:

A

Little effort and training required, so easier to collect data.
Quickly gather information, so cheaper.
Gather information from large numbers of people more efficiently, so better population validity.

54
Q

Give a WEAKNESS of Questionnaires:

A

Participants may give socially desirable answers to make themselves appear better, so data may be invalid.
Participants may misinterpret data or not understand it. They may even lie deliberately (demand characteristics), so data could be inaccurate.
Questionnaires may influence you to answer in a certain way, depending on the wording.

55
Q

What is an interview?

A

Another self-report method, involving asking a person questions directly, usually face-to-face.

56
Q

What are the two main types of interviews?

A

Structured and Unstructured

57
Q

What is a structured interview?

A

Pre-determined questions, where the interviewer sticks firmly to their scripts.

58
Q

What is an unstructured interview?

A

The interviewer starts with a few planned questions, but then creates new questions in response to the answers given by the participant.

59
Q

What is a semi-structured interview?

A

In between both structured and unstructured interviews.

60
Q

Give a STRENGTH for Structured interviews.

A

Procedure can be easily replicated/ repeated as questions are fixed.
This means data reliability can be checked.

61
Q

Give a WEAKNESS for Structured interviews?

A

The interviewer cannot deviate from their script, so information may be missed.
The interviewer’s expectations or personal characteristics may influence the answers the interviewee gives.
Participants may show a social desirability effect.

62
Q

Give a STRENGTH for Unstructured interviews.

A

Procedure allowed for greater flexibility.
Interviewer can tailor questions to the interviewee’s responses, so data can be explored in greater depth.

63
Q

Give a WEAKNESS for Unstructured interviews.

A

Interviews aren’t the same for each participant, so data reliability can’t be checked.
The interviewer’s expectations/ personal characteristics may influence the answers the interviewee gives.
Participants may show a social desirability effect.

64
Q

What is a correlation?

A

A non-experiment method that looks for the strength and direction of relationships between two co-variables, hence correlation.

65
Q

What are Co-variables?

A

The things that can be measured.
It refers to a statistical analysis of scores that are paired (ie. the Co-variables)

66
Q

Do correlations identify cause and effect?

A

Nope

67
Q

What is a positive correlation?

A

As one variable increases, so does the other. Both Co-variables increase.

68
Q

What is a negative correlation?

A

As one variable increases, the other decreases.

69
Q

What is a zero/ no correlation?

A

No relationship between the two variables.
Scatters will be all over the graph.

70
Q

What is an aim?

A

A statement of what the researcher intends to study/ the reason for carrying out the experiment.
It is written to test out a theory or hypothesis.

71
Q

What is a hypothesis?

A

A sentence-long prediction of precisely what the researcher is expecting to find out in the study. It must include the IV, DV, and be written in future tense because it’s written before the study is conducted.

72
Q

What are the two types of hypothesis?

A

Null and alternative

73
Q

What does a null hypothesis state?

A

The IV will not effect the DV.

74
Q

What does an alternative hypothesis state?

A

The IV will effect the DV.

75
Q

What are the two subtypes of alternative hypothesis?

A

Directional -> specific. States exactly how the IV affects the DV.
Non-directional -> vague. States a difference or affect will be found, but not exactly what this will be.

76
Q

What does writing a directional or non-directional alternative hypothesis depend on?

A

Prior knowledge/ research

77
Q

In what manner should you write a hypothesis?

A

Formally

78
Q

How do you start a null hypothesis?

A

‘There will be no difference in…’

79
Q

How do you start a directional hypothesis?

A

‘Participants who/ will…’

80
Q

How do you start a non-directional hypothesis?

A

‘There will be a difference in…’

81
Q

What is an extraneous variable?

A

An unwanted/ nuisance variable.
Something that can interfere with the DV in a study, causing the results to be invalid if not controlled.

82
Q

Extraneous variables can be subdivided into two types - participant and situational variables.
Describe these.

A

Participant - things about participants which can interfere with the study.
Situational - things about the environment which can interfere with the study.

83
Q

What is a confounding variable?

A

They confused the results, causing them to be invalid.

84
Q

What are investigator effects?

A

Any unwanted influence of the experimenter on the research outcome.

85
Q

What is randomisation?

A

The use of chance to control for the effect of bias.

86
Q

What is standardisation?

A

Keeping things standard for every person.
There is a list of what will happen in the study.
Standardised instructions are given to participants.
All participants should be subject to the same experiences.

87
Q

How can you control demand characteristics and investigator effects?

A

Single-blind procedures avoid demand characteristics-> participants not told details.
Double-blind procedures avoid demand characteristics and investigator effects -> the participant nor researcher conducting the study knows the main purpose or some information.

88
Q

Name the 4 experimental methods:

A

Laboratory
Field
Quasi
Natural

89
Q

What is a Laboratory experiment?

A

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.

90
Q

What is a STRENGTH of a Laboratory experiment?

A

Cause and effect relationship can be established.
Easier replication increases confidence in results.

91
Q

What is a WEAKNESS of a Laboratory experiment?

A

Loss of ecological validity (artificial experiment)
Demand characteristics-> participants more aware of observation.. unnatural behaviour

92
Q

What is a Field experiment?

A

Takes place in a natural setting, within which the researcher manipulates the IV and records the effect on the DV.

93
Q

What is a STRENGTH of a Field experiment?

A

Improved ecological validity (more natural, authentic, valid behaviour)
Less demand characteristics p, as participants are less aware.

94
Q

What is a WEAKNESS of Field experiments?

A

Loss of control of extraneous variables. Cause and effect harder to establish.
Precise replication is harder.
Ethical issues -> participants unaware.

95
Q

What is a Quasi study?

A

A study that is almost an experiment, but lacks key ingredients. The IV hasn’t been determined by anyone - the variables simply exist, such as being old or young.

96
Q

What is a STRENGTH of a Quasi study?

A

Control of extraneous variables - controlled conditions like laboratory.
It allows comparisons between different types of people.

97
Q

What is a WEAKNESS of a Quasi study?

A

Like natural ones, Quasi studies can’t randomly allocate participants to conditions and therefore there may be confounding variables.

98
Q

What is a Natural experiment?

A

Where the change in the IV isn’t brought about by the researcher, but would’ve happened even if the researcher wasn’t there.

99
Q

What is a STRENGTH of Natural experiments?

A

Study of cognitive issues allows research where an IV can’t be directly manipulated for ethical reasons.
High external validity - more realistic.

100
Q

What is a WEAKNESS of Natural experiments?

A

Loss of control - IV not directly manipulated by experimenter, so less degree of control.
Reduces likelihood of established cause and effect.
Likelihood of desired behaviour displayed -> naturally-occurring IV may be rare, thus less research opportunities.

101
Q

What is an Experimental design?

A

How we set up our participants into conditions.

102
Q

What are the three experimental designs?

A

Independent groups/ measures design
Repeated measures design
Matched pairs/ participants design

103
Q

Describe the Independent Group/ measures design:

A

This is where different participants are used in each condition of the experiment.

104
Q

Describe the Repeated measures design:

A

This is where the same participants are used in all conditions of the experiment.

105
Q

Describe the Matched pairs/ experiment design?

A

This is where there are different participants used for each condition of the experiment, but they are matched and compared directly.

106
Q

What are order effects?

A

The participant’s performance in the second condition they complete may be affected (better or worse)

107
Q

What is counterbalancing?

A

Alternating the order in which participants experience the different conditions in a repeated measures design.

108
Q

How are order effects cancelled out through counterbalancing?

A

Half participants AB, other half BA.
So order effects cancelled out through counterbalancing (ABBA)

109
Q

What is a STRENGTH of the Independent groups (measures) design?

A

No order effects
Demand characteristics aren’t as likely

110
Q

What is a STRENGTH of the Independent groups (measures) design?

A

No order effects
Demand characteristics

111
Q

What is a WEAKNESS of Independent group/ measures design?

A

Subject variables differ.
More subjects required, so less economical.

112
Q

What is a STRENGTH of Repeated measures design?

A

Individual differences which can become extraneous variables are kept constant between conditions.
Fewer subjects required, so more economical.

113
Q

What is a WEAKNESS of Repeated measures design?

A

Order effects can become constant errors.
Demand characteristics are possible

114
Q

What is a STRENGTH of Matched pairs/ participant design?

A

Subject variables are kept consistent.
Less variation between conditions, so better statistical tests can be used.
Order effects don’t occur.
Demand characteristics are less likely.
The same tests can be used.

115
Q

What is a WEAKNESS of Matched pairs/ participant design?

A

Subject variables can’t be perfectly matched in every respect.
Matching subjects is time-consuming and difficult.
More subjects required asa they’re only used once, so less economical.
