How To Read Z Table
On some z tables you will find that the area corresponding to 1 09 z score is 0 3621.
How to read z table. You can see how to find the value of 0 4265 in the full z table below. Then find the value where the row for 1 0 intersects with the column for 0 00 which is 0 8413. How to read the z table to map a z score across a z table it goes without saying that the first thing you need is the z score itself. How to use the z table. In this case it is 1 0.
First use the z table to find the value where the row for 1 0 intersects with 0 00 which is 0 1587. Then we look up a remaining number across the table on the top which is 0 09 in our example. Then follow the 0 05 column down until the row and column meet at 0 4265. First we find the first two digits on the left side of the z table. Find the 1 4 row and follow it across.
Here you want the probability that z is between 1 0 and 1 0. To find the probability that z is between two values use the z table to find the probabilities corresponding to each z value and then find the difference between the probabilities.
