Research Methods Revision
BATs describe the different types of experimental
and non-experimental techniques in Psychological research.
evaluate the strengths and weaknesses of each type of technique
Identify ethical issues and how to deal with them
Identify and use descriptive stats

Levels of measurement
Nominal: named categories (count how many in each)
Ordinal: points in order on a scale (gaps between points not equal)
Interval and Ratio: points in order with equal gaps (ratio has a real zero)
think … NOIR
Which levels of measurement are being used in each of the
following tests?

Improving eyewitness testimony

4 Research Methods 15
• Immediate access to pen and paper to jot down what they can remember
• Helping them by asking them guiding questions• Returning eyewitnesses to the
scene of the crime• Using scene reconstruction to
help them to feel the same as they did at the time
• Letting them discuss what has happened with other witnesses

Decisions about data
What do you need to decide about displaying data?
• What aspects of the data are interesting?• How can these be summarised?• How can these summaries be tabulated?• How can these summaries be illustrated?
Presenting numerical data
Summary data tables:• tables should include totals or a measure of
central tendency (mean, median or mode)• where appropriate, tables should include a
measure of spread (eg range or standard deviation)
• Remember that the choice of measures of central tendency and spread depend on the level of measurement
4 Research Methods 18
Measures of central tendency and spread
Measure of central tendency:• Mode: for nominal data• Median: for ordinal data• Mean: for interval or ratio data
Measure of spread:• Range: for ordinal data• Standard deviation: for interval or ratio data
4 Research Methods 19
Illustrating data: graphs and charts
• Bar charts• Histograms• Line graphs• Scatterplots
4 Research Methods 20
Bar charts
• used to present totals and averages
• bars must be separated in space
• title & axis labels
4 Research Methods 21
Histograms
• used to present scores, totals and averages
• bars must be adjacent
• title & axis labels
