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?

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 ().

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
