• SIMPLE HYPOTHESIS

  • Predicting a relationship b/w independent and dependent v
• COMPLEX HYPOTHESIS

  • Predicting the relationship b/w 2 or more independent and dependent v
• DIRECTIONAL HYPOTHESIS

  • Specifies not only the existence but also the expected direction of the relationship b/w independent and dependent v
• NON DIRECTIONAL HYPOTHESIS

  • Does not stipulate the direction of the relationship b/w iv and dv
• NULL HYPOTHESIS

  • Purpose: statistical analysis
• RESEARCH HYPOTHESIS
