How to use standard normal probability table
In order to properly use the above table, it's important to understand how it functions. Take for example a z-score of 1.67. One would split this number into 1.6 and .07, which provides a number to the nearest tenth (1.6) and one to the nearest hundredth (.07). A statistician would then locate … Meer weergeven The following table gives the proportion of the standard normal distribution to the left of a z-score. Remember that data values on the left represent the nearest tenth and those on the top represent values to the nearest … Meer weergeven The table may also be used to find the areas to the left of a negative z-score. To do this, drop the negative sign and look for the appropriate entry in the table.

Before technology, the \(z\)-score was looked up in a standard normal probability table (because the math involved is too cumbersome) to find the probability. In this example, a standard normal table with area to the left of the \(z\)-score was used.
