(6.3.1) z = x − μ σ. where μ = mean of the population of the x value and σ = standard deviation for the population of the x value. The z-score is normally distributed, with a mean of 0 and a standard deviation of 1. It is known as the standard normal curve. Once you have the z-score, you can look up the z-score ...

Web1. Maybe it is easier to see with a finite distribution. Suppose the values are 1, 1, 1, 2, 2, 2, 2, 2, 5, 5, 100. The median is 2 because half the values are above and half below. The mean is 1 11 ( 1 + 1 + 1 + 2 + 2 + 2 + 2 + 2 + 5 + 5 + 100) ≈ 12.2. The mode is again 2 because there are more of them than anything else.
