Use the positive Z score table below to find values on the right of the mean as can be seen in the graph alongside. Z-score table tells the total quantity of area contained to the left side of any score or value (x). For George’s example we need to use the 2nd table as his test result corresponds to a positive z-score of 0.67. Probability Density Function. The Z-table and the preceding table are related but not the same.To see the connection, find the z*-value that you need for a 95% confidence interval by using the Z-table:. F Distribution for α = 0.01. Statistical Tables A.1 NORMAL DISTRIBUTION Table A.1 represents the area or probability (a) to the right of speciﬁc z-scores for a normal distribution (see Figure A.1).

A standard normal table (also called the unit normal table or z-score table) is a mathematical table for the values of ϕ, indicating the values of the cumulative distribution function of the normal distribution.

A standard normal table, also called the unit normal table or Z table, is a mathematical table for the values of Φ, which are the values of the cumulative distribution function of the normal distribution.It is used to find the probability that a statistic is observed below, above, or between values on the standard normal distribution, and by extension, any normal distribution.
