Revision on Basic Inferential Statistics

1. Three Related Types of Distribution - Using Means as an Example
1.1 Population distribution

1.2 Sample Distribution

1.3 Sampling Distribution

1.4 From Sample Distribution to Sampling Distribution

• Central Limit Theorem

2. Inferential Statistics for Bivariate Analysis

2.1 Crosstabulation

• strength of association
• nominal-nominal : Lambda, tau-y
• ordinal-ordinal : Gamma, Somers' d, Kendall's tau-b, Kendall's tau-c
• statistical significance of association: Chi-square
• SPSS working example of Crosstabulation

• strength of association: Pearson Correlation (R)
• statistical significance of association: Z-test
• 2-tailed
• 1-tailed

• to compare and test the difference in means between 2 groups
• equal variances assumed
• equal variances NOT assumed
• SPSS working example of T-Test

• comparison of means among 3 groups or more
• F-test
