Standard deviation is a very important concept in statistics.
Why? There are always variations regarding heights, weights, eye colors or some other characteristics among individuals. No two individuals are exactly the same — even identical twins are not 100% the same in their genes.
(Recall that the term “individuals” include people, cats, dogs or anything whose characteristics a researcher is interested in exploring.)
