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

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.

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

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

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

1. Presentation & interpretation of quantitative data Number of hours day care a week Mean number of aggressive acts per week

Score on a extroversion questionnaire Frequency Draw an appropriate graph for this data

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?

3. Analysis & interpretation of correlational data Scattergrams Correlation coefficient

ParticipantSelf – rating of enjoyment of psychology Score on a question test (n 20)

Correlation coefficient Match the correlation coefficients with the correct description of the correlations Strong negative correlation Strong positive correlation 0.00Weak positive correlation No correlation Weak negative correlation

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

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

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
