Descriptive & Graphical Exercise Using SPSS[edit | edit source]
- Assumed knowledge: Allen and Bennett Chapter 3: Summarising and displaying data (pp. 19-32)
- Download and open the datafile qfsall.sav (collected using the Quick Fun Survey (html))
- Conduct the univariate and bivariate descriptive and graphical analyses outlined below.
- You can also download demonstration syntax and output files:
Univariate[edit | edit source]
Determine the level of measurement and obtain appropriate univariate descriptives and graphs to depict the nature of responses to each of the following variables:
- a8 (What is your favourite season?)
- b2 (Do you snore?)
- b4 (Do you believe in God?)
- b9 (At what age do you think you will die?)
- b13 (Femininity-Masculinity)
Statistically, you may consider using:
- frequency / % / mode
- median
- mean, SD, skewness, kurtosis
Graphically, you may consider using:
- bar graph
- pie chart
- stem and leaf plot
- boxplot
- histogram
- line graph
- error bar
Bivariate[edit | edit source]
Determine the level of measurement and examine bivariate distributions for the following relationships:
(Note that unless you are an experienced statistician you probably should conduct univariate descriptives and graphs for each variable before using them in bivariate and multivariate analyses.)
- a1 (Gender) and a4 (Favourite colour)
(nominal by nominal)- crosstabs
- clustered bar graph
- b10 (Psychology student status) and b7 (Exercise)
(nominal by ratio)- means table
- bar graph (means)
- b14 (Physical health) and b15 (Mental health)
(interval by interval)- correlation
- scatterplot - edit by going into chart editor, double-clicking on a data point and changing to bins to represent multiple data points.
- b7 (Exercise) and b9 (At what age do you think you will die?)
(ratio by ratio) - correlation
- scatterplot
