Random Sampling Versus Representative Samples
preferable to a nonrandom sample The real issue is whether a simple random sample is superior to a representative random sample This topic is seldomly discussed Most texts do not even have the word representative in their index If discussed, a stratified random sample is presented as simply another sampling technique whose use is optionalCluster sampling she puts 50 into random groups of 5 so we get 10 groups then randomly selects 5 of them and interviews everyone in those groups > 25 people are asked 2 Stratified sampling she puts 50 into Types of sampling methods Statistics (article) Khan

Quality and sampling error quantification for gold mineral
Quality assurance and quality control Quality assurance and quality control are the key components of a quality management system 8–10 Quality assurance is the collation of all actions necessary to provide adequate confidence that a process (eg sampling, test work and assaying) will satisfy the pertinent quality requirements While Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methodsMineral Processing an overview ScienceDirect Topics
