DESCRIPTION:Test-Driven Data Analysis is a methodology for reducing errors 
 in data and data analy. It is also an open-source Python package for suppo
 rting key aspects of the methodology. This tutorial will provide hands-on

  automatically) for analytical processes. It will also highlight approache
 s to avoiding errors in specific areas not amenable to software support.
