In these series of videos, we explore measures of variability; variance, standard deviation, and coefficient of variation. Two examples are demonstrated: test scores involving five fictional students and a more involved example exploring the longest field goal kicks in the NFL during the 2010 and 2011 regular seasons. You DO NOT need to understand American football to learn from the videos. :)
For the NFL example, will be calculating these measures manually using MS. Excel. So download the file and follow along!
