WebOct 9, 2024 · We compute the standard deviation for a probability distribution function the same way that we compute the standard deviation for a sample, except that after squaring x − m, we multiply by P ( x). Also we do not need to divide by n − 1. Consider the second insurance example: x. P ( x) x − x ¯. ( x − x ¯ ^2\) -10. 31/47. WebThe Z distribution is a transformation of the Normal Distribution. The function is translated so that mu becomes 0 (μ = 0). It is also compressed to the extent that sigma becomes 1 (𝜎 = 1) . This is done for several reasons: We can compare different Normal distributions by transforming them to Z distributions.
