Скачать или смотреть Business Analytics | 03 - Measures of Variability | Purdue University

Welcome to the deep dive into measures of variability! Lecturer Andy Alexander from Purdue University’s Management course, Business Analytics, provides an in-depth explanation of how we measure dispersion, or the spread of data values to better understand data distributions. Alexander elaborates on popular measures of variability including range, interquartile range, variance, and standard deviation and how each is calculated or impacted by data distributions. He further explains when to use each measure and the theoretical differences between population data and sample data in these calculations. By the end of this video, you'll gain a better sense of which measure to use based on data distribution and outliers.
