2020 - Valid Statistical Rationales for Sample Sizes used in Non-Clinical Verification, Validation, and Engineering Studies

Introduction
Examples of regulatory requirements related to sample size rationale
Sample versus Population
Statistic versus Parameter
Rationales for sample size choices when using...
Confidence Intervals
** attribute data
** variables data
Statistical Process Control C harts (e.g., XbarR)
Process Capability Indices (e.g., Cpk )
Confidence/Reliability Calculations
** attribute data
** variables data (e.g., K-tables)
Significance Tests ( using t-Tests as an example )
** when the "significance" is the desired outcome
**when "non-significance" is the desired outcome (i.e., "Power" analysis)
