## Given two sets of data, can generalize to a single question: Are the sets drawn from the same DF?

## Recall can only disprove, not prove.

## May have continuous or binned data.

## May want to compare one data set with known DF, or two unknown data sets with each other.

## Popular technique for binned data is the 2 test. For continuous data, use the KS test.
