Normal Distribution Functions in Excel A distribution is normal if the mean , median and the mode in that distribution are equal or roughly equal. The general shape of a normal distribution is bell shaped with mean in the middle where 50% of all observations are in the left and the other 50% of all observations are in the right side of the mean.

Normal and Standard Normal Distribution Functions in Excel. Regular functions (score to probability) NORM.DIST(x, mean, std. dev., cumul) Area of normal distribution from –inf to x. x = user supplied value. mean = mean of distribution. std. dev. = standard deviation of distribution. cumul: 0 = no (gives probability density),

Using EXCEL Functions In Place of Probability Tables. NORMSDIST(z): Returns the left tail probability associated with standard normal distribution z. e.g., NORMSDIST(1.65) = .950529 -- the area under the z curve up to z=1.65 is 95%. NORMSINV (P): Returns the z value so that left tail probability is P.

Normal Probability Plot of Data From an Exponential Distribution. The plot on the right is a normal probability plot of observations from an exponential distribution. The plot is convex. Appendix II: Testing for Normality By Using a Jarque-Bera Statistic. A normal probability plot test can be inconclusive when the plot pattern is not clear.

, for a normal distribution with mean = mu. standard deviation = sigma. e.g., NORMDIST (12, 5, 2, 1) = .999767. This is the probability that the random variable is less than or equal to 12 for a normal distribution with mean 5 and standard deviation 2. Note if the last argument is 0, it returns the height of the normal distribution at point . a ...
