Some notes:

  • Frequency/count data is often nominal.
  • You vary independent variables to see how they compare with each other and how dependent variables change as a result.
  • Independent measures are applied to independent people or groups (vs. repeated measure, which are applied to the same people or group).
  • Parametric data has a Normal distribution and has homogeneous variances.
