WebThe formula for weighted standard deviation is: ∑ i = 1 N w i ( x i − x ¯ ∗) 2 ( M − 1) M ∑ i = 1 N w i, where N is the number of observations. M is the number of nonzero weights. w i are the weights x i are the observations. x ¯ ∗ is the weighted mean. Remember that the formula for weighted mean is: x ¯ ∗ = ∑ i = 1 N w i x i ∑ i = 1 N w i. Web3 B. Means of Random Variables Viewing the mean of a list of (not necessarily distinct) numbers (e.g., exam scores) as a weighted mean of the distinct values occurring in the list prompts us to define the mean of a discrete numerical random variable as Mean of X = ∑f X(x)x, where the sum is over all values that X can take on.
