  1. Research Methods Revision January 2010

  2. 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

  3. Research Methods Revision Activity 1 Complete the Research Methods Glossary Use the text book to help you 10-15 mins

  4. Research Methods Revision Activity 2 In groups choose 2 types of research from…. lab experiment, natural experiment, field experiment, correlation, case study, questionnaire, interview, observation, content analysis. • For each jot down .. • A definition • 2 examples and why used in these examples • strengths/ weaknesses We will share responses in 20 mins

  5. Research Methods Revision Activity 3 Complete the ‘Defending the design’ worksheet 10 mins

  6. Research Methods Revision Activity 4 • Ethics • Match the cards • Write the answers in correct order on the blank sheet 15-20 mins

  7. Research Methods Revision Activity 5 • Ethics • Choose 2 pieces of research from the Attachments and Memory topics • Highlight the ethical issues in each • Say how they were or could have been dealt with 15-20 mins

  8. 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 4 Research Methods 8

  9. Which levels of measurement are being used in each of the following tests? Levels of measurement 4 Research Methods 9

  10. How securely attached is your child? • s/he runs to me when upset • s/he hides behind me when • frightened • s/he will play away from me • only if s/he can see me • s/he brings me things to • show me Tick all of the following which apply: 4 Research Methods 10

  11. How good is your memory? Tick one of the following: Excellent – I remember everything Very good – I remember all the important things Okay Poor – I forget some important stuff Terrible – I forget a lot 4 Research Methods 11

  12. Parasocial attachments Which of these TV and video characters are you attached to? 4 Research Methods 12

  13. How quickly does a child cry when left alone? Timed in seconds from the departure of the primary carer 4 Research Methods 13

  14. Does repetition help recall? NCL PJX FRK GMW QSZ MYC BDK Number of repetitions of a nonsense syllable and its effect on accuracy of recall 4 Research Methods 14

  15. Improving eyewitness testimony • 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 Which of the following factors do you think is most important in improving eyewitness recall? 4 Research Methods 15

  16. Are these subjects sciences? Biology Geography Psychology RE Physics 4 Research Methods 16

  17. 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? 4 Research Methods 17

  18. 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

  19. 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

  20. Illustrating data: graphs and charts • Bar charts • Histograms • Line graphs • Scatterplots 4 Research Methods 20

  21. Bar charts • used to present totals and averages • bars must be separated in space • title & axis labels 4 Research Methods 21

  22. Histograms • used to present scores, totals and averages • bars must be adjacent • title & axis labels 4 Research Methods 22

  23. Line graphs 4 Research Methods 23

  24. Scatterplots 4 Research Methods 24

  25. Scatterplots 4 Research Methods 25

  26. Scatterplots 4 Research Methods 26

  27. Scatterplots 4 Research Methods 27
