Question

Find the standard deviation of the terms. x, x, x, x, x, x, x, x, x, x + 10.

Answer 1

Answer:

Here the operator E denotes the average or expected value of X. Then the standard deviation of X is the quantity. (derived using the properties of expected value). In other words, the standard deviation σ (sigma) is the square root of the variance of X; i.e., it is the square root of the average value of (X − μ)2.
