Applied Statistics (Entire Course) - Statistics - 3.2.1 Measures of Spread or Dispersion

In this video, we'll be looking at the measures of spread or dispersion: range, variance, and standard deviation. We'll use Excel to calculate these measures, and see how they can be used to understand data. Statistics is a big subject, and this video only scratches the surface. But by understanding these three measures of dispersion, you'll be well on your way to understanding statistics in general.
