This section will answer where the values in the z table come from by going through the process of creating a z-score table. 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:. xڭYˎ�D��Wx9�S�~m#`�2��bB���H!������D+����mw��ǩ�gwW_|�ya^[J������r] This table gives Minimum Z score cut off values for selection of various University courses in each district.

Sample questions. Z-Score, also known as the standard score, indicates how many standard deviations an entity is, from the mean. Z Score Positive Negative table. 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. A.2 STUDENT’S T-DISTRIBUTION Critical values of t are shown in Table A.2 for various degrees of freedom (df). The If a z-score calculation yields a negative standardized score refer to the 1st table, when positive used the 2nd table.
