WebI am curious as to how I can write a generic method to calculate standard deviation and variance in scala. I have a generic method for calculating mean (stolen from here: Writing a generic mean function in Scala) I have tried to convert the mean calculation to get standard deviation and variance but it looks wrong to me. Web2 de jan. de 2024 · The standard deviation for percentage/proportion is: σ = p ( 1 − p) = 0.642 ( 1 − 0.642) = 0.4792 Thus when given a percentage, you can directly find the std deviation. For back tracking, we know, C I = p ± z σ N For 95%, z = 1.96, N = 427, p = 0.642 σ =? Thus use the above formula and back substitute.
