The values inside the given table represent the areas under the standard normal curve for values between 0 and the relative z-score. The table value for Z is 1 minus the value of the cumulative normal distribution. For example, the value for 1.96 is P (Z>1.96) = .0250.

It is used to find the probability that a statistic is observed below, above, or between values on the standard normal distribution, and by extension, any normal distribution.
