Normal distribution values in ExcelTo compute the values of the normal distribution function , we can use the built-in Excel function NORM.S.DIST(). For example, if we need to compute and the value is stored in
In a standard normal distribution, what {eq}z{/eq} value corresponds to {eq}17\%{/eq} of the data between the mean and the {eq}z{/eq} value? A) {eq}1.25{/eq} B) {eq}0.44{/eq} C) {eq}0.52{/eq} D) {eq}...
Video Tutorial: Normal Distribution, P-Value, Z-Scores This free Statistics video tutorial describes how to find the p-value by hand via z-scores. Explains how to use a z-score chart. Works out a couple examples including by hand and also by using a graphing calculator. Makes use of a...
Finding Probabilities from a Normal DistributionThis Googlesheet (read-only) shows how to find probabilities from a normal distribution. Simply type =norm.dist(a,b,c,true) into some cell and replace a by some x or z-value; replace b by the population mean μ; replace c by the population...
