Hotelling’s t and Steiger’s Z tests

This calculator will calculate Hotelling'sto compare two dependent correlation coefficients with one variable in common (e.g., non-nested regression models from the same population).

Directions: To conduct the test enter the following pieces of information in the yellow cells:

  • Multiple R from Model 1
  • Multiple R from Model 2
  • The correlation between the unstandardized predicted values from both Models 1 and 2.
  • Sample size, n (note: all models should be conducted using the same sample size)
  • alpha
  • # of tails of test
