Quite a large range. I am not sure what data they are basing this on, but to get an idea of the range, you need to multiply by 3 on the standard deviation. |
But roughly 90% of the samples will fall within one standard deviation. The last two deviations will only have the last 10% of the total sample population. You can disregard them in a practical application.
