How do you add standard deviations?
You cannot just add the standard deviations. Instead, you add the variances. Those are built up from the squared differences between every individual value from the mean (the squaring is done to get positive values only, and for other reasons, that I won’t delve into).

How can I calculate standard deviation in Excel?
Using the numbers listed in column A, the formula will look like this when applied: =STDEV. S(A2:A10). In return, Excel will provide the standard deviation of the applied data, as well as the average.
How do I calculate standard deviation?
To calculate the standard deviation of those numbers:
- Work out the Mean (the simple average of the numbers)
- Then for each number: subtract the Mean and square the result.
- Then work out the mean of those squared differences.
- Take the square root of that and we are done!
What is standard deviation error bars?
Error bars are graphical representations of the variability of data and used on graphs to indicate the error or uncertainty in a reported measurement.Error bars often represent one standard deviation of uncertainty, one standard error, or a particular confidence interval (e.g., a 95% interval).
Can you add averages?
If you have all of the original scores, you can get an accurate average by totalling up all the scores and dividing the total by the number of scores submitted. This is basically the same process we used to calculated the original numbers. Adding them all up, and dividing the total by 25 gives us an average of 33.
How do you add two independent standard deviations?
Sum: For any two independent random variables X and Y, if S = X + Y, the variance of S is SD^2= (X+Y)^2 . To find the standard deviation, take the square root of the variance formula: SD = sqrt(SDX^2 + SDY^2). Standard deviations do not add; use the formula or your calculator.
