      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: where a is the value of interest. This is demonstrated in the graph below for a = 0.5. The shaded area of the curve represents the probability that x is between 0 and a.
