Measures of central tendency
The mean, median, and mode answer different questions about the typical value, so the choice of one measure depends on the shape of the distribution and sensitivity to outliers.
Distribution and outliers in data
It is important to see the shape of the distribution and the individual extreme observations before drawing conclusions, because these are the ones that often break down simple interpretations of the average result.
Measures of scatter and variability
The standard deviation, range, and interquartile interval show not the center but the width of the distribution, without which the mean is often misleading.

# Описательная статистика в исследовании Средние значения, медианы, разброс и распределения нужны не как украшение таблицы, а как первый слой понимания данных до любого вывода о различиях и причинах. Эта тема раскрывает узел "Анализ данных" и нужна для того, чтобы карта не заканчивалась общим названием без внутренней структуры.
