The required size depends on how accurate indicators need to be. For PDM purposes, a 90 per cent confidence level with +/- 10 per cent confidence intervals is acceptable. The easiest way to calculate the required sample size is to use sample size calculators, which are available on the web

Provided the sample size is adequate, the risks associated with random allocation (such as failing to obtain a representative sample in a survey, or having a serious imbalance in a key characteristic between a treatment group and a control group) are calculable and hence can be managed down to an acceptable level.

NIST HB 133, 'Checking the Net Contents of Packaged Goods'
Read across from Column 1 to find the appropriate sample size in Column 2 and record this number in Box 6 of the report form. Randomly select a sample from the inspection lot. Random number tables (see Appendix B. “Random Number Tables”) or a calculator that is able to generate random numbers may be used to identify the sample.

Use of a sample size from the tables in the Chapter provides adequate documentation of the underlying inputs to the table (that is, tolerable deviation/exception rate, confidence, and expected deviation/exception rate).

SAMPLING
Divide the desired sample size by the average no. of members per cluster to get the no. of clusters to be selected (320/40=8). Select the needed no. of clusters/hospitals through random sampling. Multi-Stage Sampling A procedure carried out in phases and usually involves more than one sampling method.

Two Position Water: Line size or size using a differential pressure of 1 psi. Modulating Water: 5 PSI or twice the load pressure drop . Steam, 2-Way: maximum pressure drop across the valve at a maximum flow of 80 percent of inlet pressure up to 15 psig. Above 15 psig inlet, 42% of absolute (gage pressure + 14.7) inlet pressure.
