**Performance on standardized adaptive behavior scales that is at least three standard deviations below the mean. Example: The Adaptive Behavior Assessment System-II has a mean of 100 and a standard deviation of 15 points. A score of 55 or below would indicate adaptive behavior functioning that is three standard deviations below the mean.

Why is Standard Deviation important? | KnowsWhy.com
Standard deviation is a statistical calculation that is a measure of how much scatter (or uncertainty) there is in the data. If you round the standard deviation to one significant digit, that will tell you in which decimal place the uncertain digit of your final result lies. For example, ten quarters were weighed, and the average weight was calculated to be 5.67387 ± 0.046377 grams. Rounding the standard deviation to one significant digit gives us 0.05.

3.Suppose that you give the NAEP test to an SRS of 1000 people from a large population in which the scores have mean of 280 and standard deviation of =60. The mean of the 1000 scores will vary if you take repeated samples. A. The sampling distribution of is approximately normal. What are its mean and standard deviation?
