The SPSS procedure for conducting difference of means t-test outlined above produces two tables. Each serves a different purpose. The first table is shown in Figure 5. It simply reports summary statistics for the test variable (e.g. TVHOURS) for each of the two groups of observations (e.g.

Chapter 8.3 - Hypothesis Tests About a Mean: ˙Not Known 1.Open or create your data. It must be in the form of rows=cases and columns=variables.

SPSS: R: 1 IV with 2 levels (independent groups) interval & normal: 2 independent sample t-test: SAS: Stata: SPSS: R: ordinal or interval: Wilcoxon-Mann Whitney test: SAS: Stata: SPSS: R: categorical: Chi-square test: SAS: Stata: SPSS: R: Fisher’s exact test: SAS: Stata: SPSS: R: 1 IV with 2 or more levels (independent groups) interval & normal: one-way ANOVA: SAS: Stata: SPSS: R: ordinal or interval SPSS runs two statistical tests of normality – Kolmogorov-Smirnov and Shapiro-Wilk. If the significance value is greater than the alpha value (we’ll use.05 as our alpha value), then there is no reason to think that our data differs significantly from a normal distribution – i.e., we can reject the null hypothesis that it is non-normal. In SPSS, the Chi-Square Test of Independence is an option within the Crosstabs procedure. Recall that the Crosstabs procedure creates a contingency table or two-way table, which summarizes the distribution of two categorical variables.
