1. Data analysis and presentation EVERYONE WILL NEED A MINI-WHITEBOARD & PEN

2. Research involves the collection of data 1.What are the two different types of data that can be collected? 2.Explain how these are different.

3. What you need to know: 1.Presentation & interpretation of quantitative data - graphs, tables and scattergrams 2.Analysis & interpretation of quantitative data – measures of central tendency and dispersion 3.Analysis & interpretation of correlational data 4.Presentation of qualitative data 5.Processes involved in content analysis

4. 1. Presentation & interpretation of quantitative data Graphs and tables Bar charts Histograms Scattergrams (only used for correlational data which we will look at later)

5. 1. Presentation & interpretation of quantitative data On your mini-whiteboard: Draw a bar chart for the data above from the Loftus and Palmer study

6. 1. Presentation & interpretation of quantitative data Number of hours day care a week Mean number of aggressive acts per week 0-51 6-103 11-152 16-204 21-252 26-303 31-359

7. Score on a extroversion questionnaire Frequency 81 92 104 116 125 133 142 152 163 170 182 Draw an appropriate graph for this data

8. 2. Analysis & interpretation of quantitative data Measures of central tendency and Measures of dispersion 1.What are the measures of central tendency? 2.How do you calculate: a) the mean b) the median c)the mode 3.What are the measures of dispersion? 4.What they tell us about the data?

9. 3. Analysis & interpretation of correlational data Scattergrams Correlation coefficient

10. ParticipantSelf – rating of enjoyment of psychology Score on a question test (n 20) 11018 21020 3819 4815 5816 6713 7510 8512 942 1010

11. Correlation coefficient Match the correlation coefficients with the correct description of the correlations + 1.00Strong negative correlation + 0.44Strong positive correlation 0.00Weak positive correlation - 1.00No correlation - 0.40Weak negative correlation

12. 4. Presentation of qualitative data Themes in qualitative data which can then be turned into categories and therefore quantitative data E.g. numbers of times a behaviour or comment occurs

13. 5. Processes involved in content analysis Recap: What are the 6 processes involved in content analysis?

14. The following are individual participants’ scores on a memory test: 14, 8, 12, 10, 8, 8, 7, 6, 13, 11, 6, 6, 6, 14, 15, 13, 8, 14, 8, 11 Calculate the following: Mean, Median, Mode
