"Let’s start with the researcher’s point of view. With a normal distribution of performance (the classic bell curve), a standard deviation is simply a more precise measure of how spread out the distribution is. Somebody who is one standard deviation above average would be at the 84th percentile of the distribution. If we then turn to the labor market, a student with achievement (as measured by test performance in high school) that is one standard deviation above average can later in life expect to take in 10 to 15 percent higher earnings per year.
