Super Sample Size Me
Increased sample size, _____ Confidence Intervals
What is Decreased?
Functional, Structural, Temporal - Oh My!
What are Y to X split types?
The mathematical basis of Tukey's methodology, making it robust
What is Probability?
"It’s amazing the things you can see when you ____" - Yogi Berra
What is "look"?
Know Your Data - The formula you use to determine sample size depends on this basic determination of your data/system
What is your data type?
Continuous vs Categorical (Binomial, Poisson, Rare Event)
Y -> X : Progressive search for ______
What is Cause?
Not Solution
You've plotted your HI & LOW data, now count this
What is Endcount?
Number of repeats within the subgroup (k)
What is n?
Don't want to be caught behind the 8 ball, you know when you should get your sample size
What is during experimental design?
Wait! Did you skip the first step?
You have to confirm this, and put it on your Y to X to show you completed it
What is an MSA?
Repeatability & Reproducibility
Endcount of the "Secret Handshake"
What is 6?
3 x HI & 3 X LO, no overlap
The +/- margin of error around your sample estimate
What is confidence interval?
Non-Homogeneity happens, therefore 2 types of sample sizes should be considered
What is n & k?
n - # of repeats within each subgroup (k)
k - # of replicates of the subgroups
Try to identify this pair as soon as possible - causal category with distinctly different results in The Y
What is a Diagnostic Pair?
A narrower distribution of the Y (more overlap) requires this
What is a larger sample size?
Assignable vs Common
Cause that creates a ‘sudden’ change in a stable process; either in a nonrandom pattern or beyond predictable (historical) limits.
What is Assignable?
The minimum number of subgroups per condition to support that a difference exists with 95% confidence
What is 3?
Tukey-Duckworth Endcount Method - The probability of the 3 good lots being lower than the 3 bad lots by chance alone is 5%.
The Effect to Cause search can start with one of these "Four Questions"
What is:
What's Wrong?
What's Changed?
What's Different?
What's Happening?
The probability of a "False Positive"
What is alpha?
An output characteristic that varies and can be Measured or Assessed (can be in an acceptable or unacceptable state)
What is The Y?
