  1. >> We take the square root. If we know the area of this square, then if we take
  2. the square root, we end up with just the length of one of the sides. Since it's
  3. a square, all the side lengths are the same. So, for example, if the area of
  4. this square is 49, then each side length would be 7. That side length of the
  5. square is the standard way of measuring the variability. And it's called the
  6. standard deviation.
