ЧТО ОЗНАЧАЕТ СЛОВО CENTRAL TENDENCY
Основная тенденция
В статистике центральной тенденцией является центральное значение или типичное значение для распределения вероятности. Его иногда называют средним или просто центром распространения. Наиболее распространенными мерами центральной тенденции являются среднее арифметическое, медиана и режим. Центральную тенденцию можно вычислить как для конечного набора значений, так и для теоретического распределения, такого как нормальное распределение. Иногда авторы используют центральную тенденцию, означающую «склонность количественных данных группироваться вокруг некоторой центральной ценности». Этого значения можно было бы ожидать из обычных словарных определений словной тенденции и центральности. Эти авторы могут судить, имеет ли данные сильную или слабую центральную тенденцию, основанную на статистической дисперсии, измеряемую стандартным отклонением или чем-то аналогичным. Термин «центральная тенденция» относится к концу 1920-х годов.
