Standard Normal Table Note: An entry in the table is the area under the curve to the left of z, STANDARD NORMAL DISTRIBUTION: Table Values Represent AREA to the LEFT of the Z score. Find the cumulative probabilities for z-values from -3.4 to 3.4 in this table . The table also shows the probabilities for negative z-values and the corresponding positive z-values. The standard normal distribution table , or z table , provides probabilities for the standard normal distribution . The standard normal distribution is just a special case of the widely used normal distribution . The normal distribution is widely used for two reasons. The first reason is that it has a lot of real-world applications. Many everyday things, such as test scores, height, weight, rainfall and so on, are normally distributed. Secondly, the normal distribution is used frequently in the ...
