WebThe cumulative distribution function of a real-valued random variable is the function given by [2] : p. 77. where the right-hand side represents the probability that the random variable takes on a value less than or equal to . The probability that lies in the semi-closed interval , where , is therefore [2] : p. 84. In statistics, a standard normal table, also called the unit normal table or Z table, is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution. It is used to find the probability that a statistic is observed below, above, or between values on the standard normal distribution, … See more Formatting / layout Z tables are typically composed as follows: • The label for rows contains the integer part and the first decimal place of Z. • The label for columns contains the second decimal place of Z.

WebCumulative Distribution Function The formula for the cumulative distribution function of the standard normal distribution is \( F(x) = \int_{-\infty}^{x} \frac{e^{-x^{2}/2}} {\sqrt{2\pi}} \) Note that this integral does not exist in a simple closed formula. It is computed numerically. The following is the plot of the normal cumulative ...
