10.2. WHAT WE HAVE LEARNED IN CHAPTER 10
Six Sigma work can't be done without some understanding of probability statistics.
Letting data drive your problem solving will often save work and lead to a condensed list of solution considerations.
Using basic probability techniques on the data will help separate random results from assignable causes.
Since the sum of the probabilities of all possible outcomes always equals 1, we can often use this knowledge to simplify a problem.
Excel BINOMDIST is sufficient for doing the probability calculations, using the cumulative function to save work in doing less-than or greater-than calculations.
Examine the data carefully to make sure they are truly independent.
Although probability techniques help to focus on ...
