отбор путём случайной выборкиrandom selection (Tanya Gesse)
случайная выборкаconvenience sample (Нерепрезентативная (удобная) выборка. Иногда называется случайной, поскольку отбор элементов выборки осуществляется "случайным" образом ... a type of nonprobability sample in which the population selected is easily accessible to the researcher; available subjects are simply entered into the study without any attempt at randomization. Called also accidental sample. Found on encyclo.co.uk Alexander Demidov)
случайная выборкаconvenience sampling (Accidental sampling (sometimes known as grab, convenience sampling or opportunity sampling) is a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand. That is, a sample population selected because it is readily available and convenient, as researchers are drawing on relationships or networks to which they have easy access. The researcher using such a sample cannot scientifically make generalizations about the total population from this sample because it would not be representative enough. For example, if the interviewer was to conduct such a survey at a shopping center early in the morning on a given day, the people that he/she could interview would be limited to those given there at that given time, which would not represent the views of other members of society in such an area, if the survey was to be conducted at different times of day and several times per week. This type of sampling is most useful for pilot testing. Credibility of a researcher's results by convenience sampling will depend on convincing the reader that the sample chosen equates to a large degree of the population from which they are drawn.
