Using Charts to Present Statistical Data to Non-Statisticians

  1. 1. Using Charts to Present Your Results to Non-Statisticians Often the most effective way to describe, explore, and summarize a set of numbers… —even a very large set— is to look at pictures of those numbers. -Edward Tufte

  3. 3. Say It With Statistical Charts
  4. 4. Which Chart Tells the Best Story?
  5. 5. Chart Junk Graphical excellence gives the viewer the greatest number of ideas in the shortest time with the least ink in the smallest space. -Edward Tufte

  15. 15. No! You Need Statistical Alarms
  16. 16. Statistical Process Control in a Nutshell Reality: Every Process Varies Goal: Reduce Variation in Products and Services Types of Variation •Special Cause Variation (something changed) •Common Cause Variation (normal variation)
  17. 17. SPC in a Nutshell It’s possible to calculate statistical limits for any type of data and any pattern of variation. Using these “control” limits, it’s possible to create rules to detect special causes of variation whenever a process shifts.
