To use the z-score table, start on the left side of the table go down to 1. To be able to understand where the values come from, it is important to know about the probability density function PDF. The graph above does not show you the probability of events but their probability density.

We get the number 0. Use the positive Z score table below to find values on the right of the mean as can be seen in the graph alongside. To get the probability of an event within a given range you need to integrate. Luke Posey in Towards Data Science. Since Zoe has a higher z-score than Mike, Zoe performed better on her test.

Sure it can be combined into one single larger Z-table but that can be a bit overwhelming for a lot of beginners and it also increases the chance of human errors during calculations. This discovery was extremely useful and was put to use by other mathematicians in the years to follow. About Help Legal. Galileo discovered that the errors were symmetric in nature and in nineteenth century it was realized that even the errors showed a pattern of normal distribution. Normal Distribution Table.
