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-table and respresent the area under the bell curve to the left of z.

Inverse Z table: Calculates the Z score based on the less than or greater than probabilities α - contains the probability. Z α - the Z-value where p(x ≤ Z α) = α, critical value of the left-tailed test. Z 1-α - the Z-value where p(x ≥ Z 1-α) = α, critical value of the right-tailed test.
Use a z-table to find probabilities corresponding to ranges of z-scores and to find p-values for z-tests. The z-table is divided into two sections, negative and positive z-scores. Negative z-scores are below the mean, while positive z-scores are above the mean.

A z-table, also called standard normal table, is a table used to find the percentage of values below a given z-score in a standard normal distribution. A z-score, also known as standard score, indicates how many standard deviations away a data point is above (or below) the mean.
Understanding Z scores and utilizing the Z score table empowers us to analyze and interpret data within a standard normal distribution. Whether we are calculating probabilities, finding cut-off points, or determining proportions, the Z score table provides a valuable resource for statistical analysis.
