Normal Curve Table (DIY Project Download)

normal curve table 1

This is the bell-shaped curve of the Standard Normal Distribution. A table of normal curve equivalents may be found in most books on statistics. It shows the exact percentages between a score and the mean. Below is an exxample of such a table and how it is read. A standard normal table, also called the unit normal table or Z table, is a mathematical table for the values of, which are the values of the cumulative distribution function of the normal distribution. These probabilities are calculations of the area under the normal curve from the starting point (0 for cumulative from mean, negative infinity for cumulative and positive infinity for complementary cumulative) to Z.

normal curve table 2This is a standard table about the area found under (beneath) a Normal curve at various points along that curve. A standard normal distribution is a normal distribution with mean 0 and standard deviation 1. Areas under this curve can be found using a standard normal table (Table A in the Moore and Moore & McCabe textbooks). The calculations show the area under the standard normal distribution curve as well as the calculations. It will first show you how to interpret a Standard Normal Distribution Table.

The Z Table is located in Appendix A in the back of the text book. It starts on page 441 and gives the proportions of area under the Normal Curve for all z scores.
