Some comments on the use in research of standard statistical indicators (second post)

Abstract

Проанализированы проблемные вопросы, связанные с практическим использованием в научных исследованиях статистических оценок. Показано, что в научных исследованиях, носящих экспериментальный характер, вопросы о нормальности распределения исследуемой выборочной совокупности практически не ставятся. Представлено пошаговое описание процедуры использования критерия Стьюдента. Рекомендовано представлять статистические материалы, связанные с использованием критерия Стьюдента, в виде таблицы с указанием результата сравнения tр. с tкр.

Проаналізовано проблемні питання, пов’язані з практичним використанням у наукових дослідженнях статистичних оцінок. Показано, що в наукових дослідженнях, які носять експериментальний характер, питання щодо нормальності розподілу досліджуваної вибіркової сукупності практично не ставляться. Представлено покроковий опис процедури використання критерію Ст’юдента. Рекомендовано представляти статистичні матеріали, пов’язані з використанням критерію Ст’юдента, у вигляді таблиці із зазначенням результату порівняння tр з tкр.

We analyzed issues related to the practical use of statistics in research evaluations. Shown in scientific studies that are experimental in nature, the question of normality of distribution of the study sample are virtually. Submitted by-step description of the procedure using Student's t test. Recommended represent statistical data related to the use of Student's t test, a table indicating the result of the comparison of tes. with tcr..
