Statistical Test

What sort of statistical tests should I do?

There are lots of options! Appropriate testing depends on aspects of your design:

  • how many conditions
  • what type of measurements
as well as on how the data itself turned out:
  • is it normally distributed
  • are the standard deviations the same among conditions

Make friends with your neighborhood applied-math or experimental-sciences weenies. For human-computer interaction issues, your local psychology department is probably full of friends.
