Coefficient of variation gives us an idea about the variability in the process, especially when looking at sales and demand. Methods work in different ways, and the results from each might not be directly comparable – getting it right is therefore critical for your work or research. These descriptive statistics act as the foundation for … Those four topics are : Measures of Frequency; Measures of Central Tendency; Measures of Variability; Measures of Shape . We plot inertia in the Y axis and K in the Y axis. This is a good opportunity to get inspired with new dataviz techniques that you could apply on your data.
