Sampling Plan
•Issues when using a
sequential sampling plan
–Design stage
•Boundaries to satisfy
desired operating characteristics
»E.g., type I error,
power, sample size requirements
–Monitoring stage
•Flexible
implementation of the stopping rule to account for assumptions
made at design stage
»E.g., sample size
adjustment to account for observed variance
–Analysis stage
•Providing inference
based on true sampling distribution of test statistics
