1. Looking for Differences

   • One Sample t test
     • 1 IV and 1 condition. Compares one set of scores to a reference score
   • T tests
     • Have 1 independent variable and 2 conditions
     • Independent t test
     • Repeated t test
   • One-Way ANOVA
     • Has 1 Independent variable and 3+ conditions
     • One-way Independent ANOVA
     • One-Way Repeated ANOVA
   • Factorial ANOVA
     • Has 2+ Independent variables
     • Two-way Independent ANOVA (P's are independent for each IV)
     • Two-way Repeated ANOVA (P's are repeated for each IV)
     • Two-way Mixed Design ANOVA (P's are both repeated for 1 IV and independent for 1)
     • Complex ANOVA 'Three-Way Mixed'

2. Looking for Relationship

   • Correlations (both variables MUST be continuous)
     • Pearson's
     • Partial (controls for confound)
   • Regressions
     • Continuous OUTCOME
       • Simultaneous (enter all predictors into the model)
       • Stepwise (Extract significant predictors in order of importance)
       • Hierarchical (control for confound then assess predictors)
     • Binary OUTCOME
       • Logistic (predictor can be continuous OR categorical)
