A GENERAL SAMPLING THEORY

A GENERAL THEORY IS PRESENTED FOR THE SAMPLING OF MATERIALS AND STATISTICAL POPULATIONS THAT ARE ENCOUNTERED IN THE FIELD OF ENGINEERING AND OTHER DISCIPLINES. THE BASIC CONCEPT OF THIS THEORY IS THAT THE VARIALBILITY OF A MATERIAL CONSIGMENT OR ANY OTHER POPULATION CAN BE EXPRESSED BY TWO VARIANCE COMPONETS THAT ARE CONSTANTS AND REFLECT STATISTICAL PROPERTIES OF THE MATERIAL IN THE SAME WAY THAT OTHER MATERIAL CONSTANTS REFLECT CERTAIN PHYSICAL AND CHEMICAL PROPERTIES OF MATERIALS. THESE VARIANCE COMPONENTS OR SAMPLING CONSTANTS ARE USED FOR DESIGNING SAMPLE EXPERIMENTS AND, MORE SPECIFICALLY, FOR DETERMINING IN ADVANCE THE PRECISION OF SAMPLING EXPERIMENTS AS A FUNCTION OF SAMPLE SIZE AND THE NUMBER OF INCREMENTS. APPLICATION OF THE METHOD IS ILLUSTRATED WITH 12 EXAMPLES THAT COVER A LARGE NUMBER OF MATERIALS AND CONDITIONS. CONDENSED INSTRUCTIONS ARE PRESENTED IN A TABLE. /AUTHOR/
