Hello, I have a "peer" group of distributions with the following data
Distribution1 : Mean-M1, Standard Deviation-SD1, Total number of data points - N1 Distribution2 : Mean-M2, Standard Deviation-SD2 Total number of data points - N2 Distribution3 : Mean-M3, Standard Deviation-SD3, Total number of data points - N3 ... Distributionn : Mean-Mn, Standard Deviation-SDn, Total number of data points - Nn What is the most accurate way to determine the overall mean and the standard deviation of the above disributions. Also, I need to remove any distributions that are not similar to the rest of the distributions in the "peer" group.
