The following chart summarizes how the Statistical Test functions handle various types of input. Those cases with the note “should be normal numeric” will give warnings for any type of input that is not standard numeric (i.e., for character data, dates, big integers or decimals, etc.).
In the table below, cat is an abbreviation for categorical, num for numeric and bignum for big integers or decimals:
