The Data is Revolting- Episode 3 (Part 1)

Understanding variation in you data, and getting comfortable with what that variation does and does not mean is crucial for meaningful improvement. Too much for one episode, I'm splitting Episode 3 into two parts to have more manageable chunks of info to process. And hopefully after both parts, you will be ready to one of two things. Either take every Year-over-Year or Pie chart you are handed and throw it in the trash or, take that as an opportunity to say "can I get the data that went into this chart broken down into time sequence" and start showing people what real QI looks like!
