Standard Normal Distribution Table - Math is Fun
WebAreas under the curve represent proportions of scores. We can indicate these proportions as decimals, fractions or percentages. The whole area under the curve is 1 or 100 percent. Because normal distributions are well understood and tabulated, we can work out pro-portions of observations within intervals for normally distributed variables. WebThe Z score itself is a statistical measurement of the number of standard deviations from the mean of a normal distribution. Using the z-chart table. When z = -1.0, we see that z = 0.1587. When z = -2.0, we see that z = 0.228. By subtracting both we can find the area under the standard normal distribution curve. Area = 0.228 - 0.1587.
