25
What are the 3 types of graphing?
Bar, Histogram and Scattergram
26
What are 2 strengths and a limitations of using secondary data?
Strength - Inexpensive - Easy access Limitation - out of data information - False information
27
What are 2 strength of using correlations?
Can study relationships between variables that occur naturally Relatively quick and economical to carry out
28
What are 2 strengths and a limitations of using Primary data?
Strengths - Authenticity - Fits the job Limitations - Time consuming to collect - More effort and potentially more costly
29
What are 2 limitations of using correlations?
Can only tell us how but not why there is this pattern There may also be another untested variable involved (intervening variable)
30
what are 3 key things needed to write good questions for a questionnaire?
Avoid overuse of jargon Emotive language / Leading questions Double negative questions
31
What are 2 strength of a structured interview?
Easy to replicate Limits investigator effects
32
What are 2 limitation of an unstructured interview?
More chance of investigator bias Lots of unnecessary information to sort through (Time-consuming)
32
What is a strength of an unstructured interview?
More flexible with follow up questions (More info discovered)
33
What are 2 limitation of a structured interview?
Limits richness in data Limit unexpected information
34
What are 4 strength of a questionnaire?
- Cost effective - Quick to occur (investigator does not need to be present) - Information straight to analyse - Easy to form graphs and charts from
35
What are the 2 limitations of questionnaires?
- Demand characteristic - Social desirability bias - Acquiescence bias
36
What does the term 'Acquiescence bias' mean?
Just continuously agreeing/disagreeing on the terms of the questionnaire regardless of the question.
37
What does the term 'Social desirability bias' mean?
Responders may not always tell the truth because they would rather appear in a positive light therefore changing their answers
38
what does it mean by objectivity?
minimalisation of any personal bias so that it doesnt influence/distort the research process
39
# RPTFO What are the five features of science?
- Replicability - Paradigms - Theory construction - Falsibility - Objectivity and the Empirical method
40
What is a paradigm?
A set of shared assumptions and agreed methods within a scientific discipline
41
What is a paradigm shift?
Scientific revolution that results in a significant shift in beliefs.
42
Name a type of external validity?
Ecological validity
43
What is ecological validity?
Generalising findings from a study to other settings (real-life applications in every day life)
44
What is face validity?
Measuring 'on the face of it'
45
What is a concurrent validity?
When results of a study closely match another recognised/well-established test.
46
What are 2 ways of assessing reliability?
Test-retest Inter-observer reliability
47
What does it mean by Inter-observer reliability?
The extent to which at least 2 observers are in agreement of a studies results.
48
What is the way to improve reliability within questionnaires?
The test retest method
49
What is the way to improve reliability within interviews?
Use the same interviewer each time keep them trained to avoid leading questions structured interview to avoid bias
50
What is the way to improve reliability within observations?
Operationalise the behaviour categories
51
What is the way to improve reliability within experiments?
standardisation
52
What are the 3 main aims of peer review? (FAV)
Funding allocation Validate the quality/relevance of the research Amendments suggestions
53

A type of content analysis where you identify the themes/recurrent patterns
70
What is a strength and limitation of content-analysis?
Strength -Can circumnavigate many ethical issues associated with psychological research No permission needed so high external validity Produced both types of data depending on research aims Limitation - As it is indirect, communications are analysed outside the context within which occurred. also lack of objective validity
71
6 features of a scientific report?
Abstract Introduction Method Results Discussion Referencing
72
Whos research does not have falsibility?
Freud
73
What are the 2 economic implications?
Employment and NHS
74
What are the 2 measure of dispersion?
Range and standard deviation
75
What are strengths of covert observations?
Removes demand characteristics allowing an increase in validity
76
What is a weakness of covert observations?
Ethics, rights to privacy
77
What are strengths of naturalistic observations?
High external ability, can be generalised to real world settings.
78
What is content analysis?
A method of quantifying qualitative content vie categorisation/coding
