      Standard deviation and variance are measures of dispersion, which indicate how spread out a set of numbers is from the average value. Think of it like a bunch of apples: if you have a large, juicy apple, a medium-sized apple, and a small apple, the average size would be somewhere in the middle. The standard deviation and variance would tell you how far each apple is from this average size.
