Confidence Limits and Tests of Significance

  • Ken Stout

Abstract

When samples are taken from unknown populations, assumptions cannot be made that the evidence of a small sample is definitely a true representation of the population (or batch). Clearly, although the samples have been removed from the population, and therefore are part of that population, they may not be totally representative. Consequently, it is important to establish the ‘confidence’ one has in a sample and, by defining the ‘confidence’, some information on the character of the population is gained.
