  • Data is normally distributed
  • Multiple dependent variables

    • Analyze
    • General Linear Modeling
    • Multivariate
      • Dependent variables in the dependent list
      • Independent variable(s) in the fixed factor
      • Add covariate in the covariate box
  • Multivariate
    • Options
    • Click on the IV under Factors and Factor interactions and move to display means for:
    • Continue
    • Ok

Output

  • Check the Multivariate test box, see Wilk’s Lambda score for significance level
    • If Wilk’s Lambda is significant, then a statistically significant difference can be established in terms of your IV and DV
    • If Wilk’s Lambda is not significant then there is no statistically significant difference between the variables
