Mar 16, 2024 · Learn more about Empirical Cumulative Distribution Function Plots. These graphs help you compare an observed cumulative distribution to a fitted distribution.

In probability theory and statistics, the cumulative distribution function (CDF) of a real-valued random variable, or just distribution function of , evaluated at , is the probability that will take a value less than or equal to . [1]

Tables of the Normal Cumulative Distribution The table below gives the probability p that a Standard Normal random variable Z (ie mean = 0 and variance = 1) is less than or equal to z .

The table below contains the area under the standard normal curve from 0 to z. This can be used to compute the cumulative distribution function values for the standard normal distribution . The table utilizes the symmetry of the normal distribution, so what in fact is given is

The table value for Z is the value of the cumulative normal distribution. For example, the value for 1.96 is P(Z<1.96) = .9750. Find the p-value using the standard normal table.

The table reports the area under the standard normal curve to the left of the value z.

The Cumulative Distribution Function (CDF) is the probability that the random variable X will take a value less than or equal to x. The following table summarizes common continuous and discrete distributions, showing the cumulative function and its parameters.
