Z is the standard normal random variable. The table value for Z is the value of the cumulative normal distribution at z. This is the left-tailed normal table. As z-value increases, the normal table value also increases. If you noticed there are two z-tables with negative and positive values. If a z-score calculation yields a negative standardized score refer to the 1st table, when positive used the 2nd table. For George’s example we need to use the 2nd table as his test result corresponds to a positive z-score of 0.67. The z-scores to the right of the mean are positive and the z-scores to the left of the mean are negative. If you look up the score in the z-table, you can tell what percentage of the population is above or below your score. The table below shows a z-score of 2.0 highlighted, showing .9772 (which converts to 97.72%).

It is important to keep in mind that if you have a negative z-score, you can simply use a table that contains negative z-scores. You can find one here. How to create a Z-Table (Heavy Math) Cumulative probabilities for POSITIVE z-values are shown in the following table: Title: std normal table.xls Created Date: 9/8/2005 8:46:41 AM Online statistics table calculator lets you compute z-scores, t-table values, chi-square, etc. Much faster & more accurate than book tables. For research, homework, or an online statistics class. So easy it's almost cheating. And this thing right here, we've learned it before, is a Z-score, or when we're dealing with an actual statistic when it's derived from the sample mean statistic, we call this a Z-statistic. And then we could look it up in a Z-table or in a normal distribution table to say what's the probability of getting a value of this Z or greater. Source: Frederick Mosteller and Robert E. K.
