Calculating confidence interval of RSD% with confidence level of 95%

[#1]

Hi,

Anyone knows how to calculate confidence interval of RSD% with confidence level of 95%?

I have data set with 6-12 datapoints. I would like to calculate confidence interval of RSD% to investigate the distributions over time.

Thanks in advance,

Hi @ghteymoori1362 : Here ya go. CV is Coefficient of Variation which is Sigma/mean. Just multiply by 100 to get % RSD.

Edit: Appears it already multiplies by 100 so no need to do that. You can verify this via the mean and SD.
