To grasp the concept of sigma, let's consider a simple example. Imagine a set of exam scores for a class. If the mean score is 80, and the standard deviation (sigma) is 10, it means that most students scored between 70 and 90 (one standard deviation above or below the mean). Sigma helps us understand how spread out the data is.
