ЧТО ОЗНАЧАЕТ СЛОВО BIASED SAMPLE
Отклонение выборки
В статистике смещение выборки представляет собой предвзятость, в которой выборка собирается таким образом, что некоторые члены предполагаемой группы населения с меньшей вероятностью будут включены, чем другие. Это приводит к предвзятой выборке, неслучайной выборке населения, в которой все люди или экземпляры не были одинаково вероятны. Если это не учтено, результаты могут быть ошибочно отнесены к изучаемому явлению, а не к методу отбора проб. Медицинские источники иногда ссылаются на предвзятость выборки как на предвзятость. Уклонение от оценки имеет в основном одно и то же определение, но по-прежнему иногда классифицируется как отдельный тип предвзятости.
