  Videos on Data Analysis - using SPSS:

in PDF format Chi-square
(how to do a very simple chi-square test (=is there a significant difference?))
in PDF format Chi-square - not 50/50
(here we see how chi-square can be used to see if there is a change over time)
in PDF format Correlation - Spearman
(we look for significant patterns (=not for significant differences) and our data is categorical/non-parametric)
in PDF format Correlation - Pearson
(we look for significant patterns (=not for significant differences) and our data is scalar/parametric)
in PDF format Mann Whitney
(we look for significant differences due to a factor, our data is non-parametric and we have two groups for our factor)
in PDF format Independent t-test
(we look for significant differences due to a factor, our data is parametric and we have two groups for our factor)
in PDF format Wilcoxon
(we look for significant differences due to a factor, our data - which we collected twice - is non-parametric and we have two groups for our factor)
in PDF format Paired t-test
(we look for significant differences due to a factor, our data - which we collected twice - is parametric and we have two groups for our factor)
in PDF format Kruskal-Wallis
(we look for significant differences due to a factor, our data is non-parametric and we have more than two groups for our factor)
in PDF format One-way independent Anova (including post-hoc test)
(we look for significant differences due to a factor, our data is parametric and we have more than two groups for our factor)
in PDF format Friedman
(we look for significant differences due to a factor, our data - which we collected twice - is non-parametric and we have more than two groups for our factor)
in PDF format Two-way independent Anova (with interaction)
(we look for significant differences due to two factors, our data is parametric)
in PDF format Two-way independent Anova (without interaction)
(we look for significant differences due to two factors, our data is parametric)

  PDFs on Research Design:

in PDF format Recruiting a Representative Sample
(including how to statistically test sample sizes)
in PDF format Ethics is Essential
(including a template information and consent form)
in PDF format Normalisation in Discourse Analysis
(including how to statistically (dis-)prove differences between two or more discourses)
