Statistics Flashcards
What is meant by the term primary data? (2)
- Gathered first hand from participants themselves
- Specific to aim of study
What is meant by the term secondary data? (2)
- Previously collected by third party
- Not specific to aim of study
What is meant by the term meta analysis (2)
- Uses secondary data
- Gains data from large number of studies that have investigated the same research questions and combines this to make conclusions about behaviour
What is a content analysis? (2)
- Analysing qualitative data by changing qualitative data into quantitative data
- Done by identifying meaningful codes and presenting data in a graph
How is a content analysis carried out? (4)
- Read/view video or transcript
- Identify/create coding categories
- Re-read transcript or re-view video and tally each time coding category appears
- Present quantitative data in table or graph
What is a thematic analysis? (2)
- Analysing qualitative data by identifying emergent themes
- Allows us to present data in qualitative format
How is a thematic analysis carried out? (4)
- Watch video and create transcript
- Read and re-read transcript. Identify coding categories that crop up repeatedly
- Combine codes to reduce number of codes into three or four themes
- Present data in qualitative format
What is a type one error? (2)
- Researcher uses lenient p value, thinks the results are significant when they are actually due to chance
- Wrongly accept alternate hypothesis and wrongly reject null
What is a type one error? (2)
- Researcher uses lenient p value, thinks the results are significant when they are actually due to chance
- Wrongly accept alternate hypothesis and wrongly reject null
What is a type 2 error? (2)
- Researcher uses stringent p value, thinks the results are not significant when they could be significant
- Wrongly accept null and wrongly reject alternate hypothesis
Why do psychologists use the 5% significance level? (2)
- Strikes a balance between risk of making a type one and type two error
- Conventional significance level
What is the purpose of an abstract? (3)
- Allows reader to gain overview of the study including aims, hypothesis, methods, results and conclusions
- First part of a psychological report
- Reported in a single paragraph of 150-250 words
What is the purpose of an introduction? (2)
- Gives background on relevant theories and studies
- To explain how aims and hypothesis developed
What is the purpose of the results section? (2)
- Present overall summary of findings
- Rather than reviewing raw data
What is the purpose of the discussion session? (2)
- Discuss findings
- Suggest possible uses and future areas of research
How to reference an article?
Author name - date - title of article, journal title, volume, issue number, page number
How to reference a book?
Author last name, first initial (Date). title of book. place of publication:publisher
What is meant by the term peer review? (2)
- Psychological research, before publication, are subjected to independent scrutiny by other psychologists in a similar field
- Consider research in terms of validity, significance and originality
Describe the purpose of a peer review (2)
- Prevent dissemination of irrelevant findings
- Determines whether research should receive funding
Evaluate the peer review process. Give problems … (3)
- Tendency to favour research which comes from prestigious universities
- Tendency to favour research which comes from male researchers
- Bias towards positive findings
Explain what is meant by a paradigm shift (3)
- Paradigm is a set of shared assumptions and beliefs about how behaviour is studied
- A shift occurs where members of a scientific community change from one established way of studying a behaviour to a new way due to new evidence
- This shift leads to a ‘scientific revolution’
Explain what is meant by theory construction (2)
- Allows us to make a prediction about behaviour and create a hypothesis and test it empirically
- Allows progression through scientific cycle of enquiry
Explain what is meant by empirical methods (1)
- Information gained through direct observation or experiment rather than opinion
Explain what is meant by objectivity (2)
- Research unaffected by expectations of researcher
- Uses factual measurements and controlled conditions to reduce subjectivity
