In this lecture (16.November 2006) we experiment more detailed with statistical tests in SPSS.
Every scale level has its own test methods, e.g. for differential testing:
nominal scale -> chi square test
ordinal scale -> Man-whitney U-test, Kruskal-Wallis test
metric scale -> Variance Analysis (for a test on the normal distribution: Kolmogorov-Smirnov-test)

The procedure in statistical testing is like described earlier: formulation of null and alternative hypothesis, definition of probability and significance level, actual test, interpretation of results.
