How Many Z Tables Are There
In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of Φ, 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. Since probability.
There are two Z-tables: the positive Z. Use the positive Z score table below to find values on the right of the mean as can be seen in the graph alongside. Corresponding values which are greater than the mean are marked with a positive score in the z.
There are two main types of Z Score Tables: positive and negative. The positive z table lists probabilities for z-scores above the mean (right side of the curve). On the other hand, the negative z table lists probabilities for z-scores below the mean (left side of the curve).

The table below shows the area under the standard normal curve to the left of z. Related: How to use the Z Table (With Examples). There are two methods to read the Z-table: Case 1: Use the Z-table to see the area under the value (x) The first column in the Z-table top row corresponds to the Z-values and all the numbers in the middle correspond to the areas.
For example, a Z-score of -1.53 has an area of 0.0630 to the left of it. In other words, p (Z. Here is the data behind the bell.
