Description:

The data give the success rates of two methods of treating kidney stones: open surgery methods, and percutaneous nephrolithotomy.

There are eight observations on four variables.

Variables:

Counts	The number of subjects in the given classification
Group	Whether the subject has kidney stones with mean diameter less than 2cm (Small) or greater than or equal to 2cm (Large)
Method	The treatment method: Either A (an open surgery method) or B (percutaneous nephrolithotomy).
Outcome	The outcome of the stated treatment: Either Success if the treatment was successful, or Failure if unsuccessful.

Data Quality:

There are no missing values.

Notes: The given data are a subset of that reported by Charig et al., who also incude two other methods of treatment, and also break up the open surgery methods into three sub-groups. The two methods here were chosen because they demonstrate Simpson's paradox.
