This is one version of a z table. It gives the probability that a standard normal random variable, Z, will not exceed a given number, z. Equivalently, it gives the probability that any normal random variable will not exceed a value more than a given number of standard deviations above its mean. See Z-score for more information. To look up the probability of Z being less than 1.96, for example, look in the row for 1.9 and the column for 0.06; the probability is 0.9750.
