This article discusses the conditional scheme of a program for calculating the main statistical characteristics of a sample. Keywords: IDLE (Python 3.12.3), FILE, ENTER, calculation of the coefficient of variation, coefficient of variation. УСЛОВНАЯ СХЕМА ПРОГРАММЫ РАСЧЕТА ОСНОВНЫХ СТАТИСТИЧЕСКИХ ХАРАКТЕРИСТИК ВЫБОРКИ. Аннотация. В данной статье рассматривается условная схема программы расчета основных статистических характеристик выборки. Ключевые слова: IDLE (Python 3.12.3), FILE, ENTER, расчет коэффициента вариации, коэффициент вариации.
