Analysis and Interpretation: Multiple Variables Simultaneously Chapter 13

Univariate v. Multivariate

Cross-Tabulation Shows relationships between two or more variables Pearson chi-square test Nominal level

Cross-Tabulation

Independent Samples T-Test for Means Determine whether two groups differ on some characteristic Examples: Genders, Yes/No

Independent Samples T-Test for Means

Pearson Correlation Coefficient Degree of association between continuous variables -1------------------0------------------1 Does NOT mean causation

Pearson Correlation Coefficient

Regression Analysis Relationship between one or more predictor variable and an outcome variable Coefficient of multiple determination R2
