:::Each individual is chosen [[w:randomization|randomly]] and entirely by chance, such that each individual has the same [[w:probability|probability]] of being chosen at any stage during the sampling process, and each subset of ''k'' individuals has the same probability of being chosen for the sample as any other subset of ''k'' individuals. This process and technique is known as '''simple random sampling''', and should not be confused with [[w:Systematic sampling|systematic random sampling]]. A simple random sample is an unbiased surveying technique.

'''[[w:Statistics|Statistics]]''' is the study of the collection, organization, analysis, interpretation and presentation of data. It deals with all aspects of data including the planning of data collection in terms of the design of [[w:statistical survey|survey]]s and [[w:experimental design|experiments]] ( Wikipedia ) | '''[[w:Statistics|Statistics]]''' is the study of the collection, organization, analysis, interpretation and presentation of data.
