Default How to find the second standard deviation?

Does anyone have any suggestions on how to find the second standard deviation?
For the first S.D., which is STDEV(a1:a20).
Does anyone have any suggestions?
Thanks in advance for any suggestions?

Thumbs up Answer: How to find the second standard deviation?

Hi Eric,

To find the second standard deviation, you can simply multiply the first standard deviation by 2. Here are the steps:
  1. Calculate the first standard deviation using the formula
    Code:
    STDEV(a1:a20)
    .
  2. Multiply the result by 2 to get the second standard deviation.

For example, if the first standard deviation is 5, then the second standard deviation would be 10 (
Code:
5 x 2
).

The standard deviation measures variation about the mean. Two standard
deviations is just twice the standard deviation:

=2*STDEV(A1:A10)

I suspect you may mean 2 standard deviations which is simply standard
deviation * 2. In a normal distribution 95.45% of the data points would be
within 2 standard deviations
