Web21 de jan. de 2024 · Definition 6.3. 1: z-score. (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. … WebExample 6.1. Suppose X ~ N (5, 6). This says that X is a normally distributed random variable with mean μ = 5 and standard deviation σ = 6. Suppose x = 17. Then: z = x – μ σ = 17 – 5 6 = 2. This means that x = 17 is two standard deviations (2 σ) above or to the right of the mean μ = 5.

Normal distribution - Wikipedia

WebIf a variable is normally distributed in some population, then it should be roughly normally distributed in some sample as well. A first check -simple and solid- is inspecting its frequency distribution from a histogram. In SPSS, we can very easily add normal curves to histograms. This normal curve is given the same mean and SD as the observed ... Web1. It could mean a lot or it could mean nothing.
