![]() This table gives a probability that a statistic is less than Z (i.e. To find the z-score for the standard normal distribution that corresponds to the given probability, look up the values in a standard table and find the closest match. Table of Standard Normal Probabilities for Negative Z-scores z 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 -3.4 0.0003 0.0003 0.0003 0.0003 0.0003 0.0003 0.0003. ![]() Note that for z = 1, 2, 3, one obtains (after multiplying by 2 to account for the interval) the results f( z) = 0.6827, 0.9545, 0.9974, If the area is halfway between two entries, use the z- score halfway between the corresponding z- scores. It shows you the percent of population: between 0 and Z (option '0 to Z') less than Z (option 'Up to Z') greater than Z (option 'Z onwards') It only display values to 0.01. Use the standard normal table to find the z- score that corresponds to the cumulative area.If the area is not in the 0.9015 table, use the entry closest to the area. It is a Normal Distribution with mean 0 and standard deviation 1. If X is a random variable from a normal distribution with mean μ and standard deviation σ, its Z-score may be calculated from X by subtracting μ and dividing by the standard deviation: This is the 'bell-shaped' curve of the Standard Normal Distribution.
