Statistical Measures
T-test statistical tests can only be used when you are comparing one
categorical variable (with two groups or categories) and one continuous
variable. You need to choose a statistical test that is appropriate for
your predictor and outcome variables. If you need more help, you can
revisit the SmartGuides or you can email a mentor for help.

I found that girls of any age have more or less tattoos.
