Example of how to use the Z-table

The Z-value is found by combining the numbers in the first column and the first row.

For example, the probability for getting a z-value smaller than 1.85 is found by finding the number in the table where the row is 1.8 and the column is 0.05.

In the example table below, the selected row, column, and cell are highlighted. The selected cell corresponds to z = 1.85.

Example lookup: z = 1.85
