Normal Distribution CalculatorEnter the raw score, mean, and standard deviation to find the probability of getting a number above or below that score using the normal distribution calculator below. Mean (μ): Standard Deviation (σ): Raw Score (x): ...
Normal Distribution Formula: The probabilities are determined by the formulas $$\begin{align} P(X \leq X_1)&=\frac1{\sqrt{2\pi \sigma^2}}\int_{-\infty}^{X_1} e^{-\frac{(x-\mu)^2}{2\sigma^2 }}dx\\ P(X \geq X_1)&=\frac1{\sqrt{2\pi \sigma^2}}\int^{\infty}_...

The number of standard deviations from the mean is also called the "Standard Score", "sigma" or "z-score". Get used to those words!Example: In that same school one of your friends is 1.85m tall You can see on the bell curve that 1.85m is 3 standard deviations from the mean of ...
摘要: This article describes how a graphics calculator can be used by students who are learning about the Normal distribution. It also discusses the implications of replacing the use of statistical tables.DOI: 10.1111/1467-9639.00039 年份: 2001 ...
A normal distribution is one of underlying assumptions of a lot of statistical procedures. In nature, every outcome that depends on the sum of many independent events will approximate the Gaussian distribution after some time, if respected the assumptio
Lognormal distributionEGPMODPMOPurpose The purpose of this paper is to propose an approach for studying the Six Sigma metrics when the underlying distribution is lognormal. Design/methodology/approach The Six Sigma metrics are commonly available for normal processes that are run in the long run. ...
