The sample size is the number of units or observations that you select from a larger population to measure or test for quality. The sample size affects the accuracy and precision of your results ...

How can you ensure that your sample size is appropriate for quality control? Here are some factors and steps to consider. The first factor to consider is the purpose of your sampling. What are you ...

Refer to Kish (1987, 1965), Kalton (1983), and Cochran (1977) for more information on probability sampling. In probability proportional to size (PPS) sampling, a unit's selection probability is ...

If you specify the option METHOD=PPS, PROC SURVEYSELECT selects units with probability proportional to size and without replacement ... For a stratified design, n now denotes the sample size for the ...

A random sample from each stratum would be taken in a number proportional to the stratum’s size compared with the population. These subsets of the strata would then be pooled to form a random ...

The proportion of responsive documents in the sample serves ... fixate on a certain sample size or confidence interval for elusion testing as it is to do so for a control set.

This sampling interval is calculated by dividing the population size by the desired sample size ... systematic sampling provides an increased degree of control compared to other sampling ...

Abstract: This article addresses the problem of observer-based fuzzy proportional-integral-derivative (PID) control for a class of nonlinear systems subject to degraded measurements and randomly ...
