Inferential Statistics Significance Test Crosstabulation/Chi-square Test t-Test F-Test/ANOVA I. What Does Bivariate Analysis Do? 1.Estimate and test the significance of the difference in an interval DV between/among groups (Compare means based on t-test or F-test) 2.Estimate and test the significance of the difference in a nominal DV between/among groups 2(Crosstabulations based on ? test) 3.Estimate and test the significance of the correlations between an interval IV and an interval DV (Correlation or Regression based on t-test or F-test) 3 Statistical Techniques for Bivariate Analysis IV DV Dichotomous Multinomial Continuous Dichotomous Logistic ?2 Test of Regression Multinomial Crosstabulation Analysis Multinomial Logistic Regression Continuous t-Test ANOVA (F-Correlation Test) /OLS Regression 4 Statistical Techniques for Multi-IVs and Single DV IVs DV Dichotomous Multinomial Continuous Mixed Dichotomous Logistic Regression Log-linear Modeling Multinomial Multinomial Logistic Regression Continuous ANOVA OLS Regression /ANCOVA 5 Statistical Techniques for Multi-IVs and Multi-DVs IVs DVs Dichotomous Multinomial Continuous Mixed Dichotomous Not available; convert Latent Categorical continuous IVs to Multinomial Analysis (LCA) categorical and then use LCA Continuous General Linear Modeling MANCOVA (GLM) /MANCOVA /Structural Equation Modeling (SEM) 6 Probability Theory, Sampling Distributions, and Estimates of Sampling Error ?Sampling Distribution oSingle most important concept in inferential statistics oDefinition: The theoretical, probabilistic distribution of a statistic for all possible samples of a given size (N). oThe sampling distribution is a theoretical distribution. ?Every application of inferentia
