This is the "bell-shaped" curve of the Standard Normal Distribution. Standard Normal Distribution Table. The standard normal distribution, represented by the letter Z, is the normal distribution having a mean of 0 and a standard deviation of 1. It is a Normal Distribution with mean 0 and standard deviation 1. The full normal distribution table, with precision up to 5 decimal point for probability values (including those for negative values), can be found here. STANDARD NORMAL DISTRIBUTION: Table Values Represent AREA to the LEFT of the Z score. Let’s see some real life examples.
