The number and type of possible statistical tests in experimental science can be bewildering. Luckily choosing the right test can be made alot easier by first considering the question: Is your data categorical or continuous? * Categorical data* is typically percentage or frequency data binned into 2 or more categories or names.

*is typically measurement data where there is a well defined relationship between the values (i.e. numerical data)*
