For example, let’s say we need t find the area between z-scores of -.75 and 1.21. Next, we’ll subtract the smaller area from the larger area. First, we’ll find the area to the left of each z-score. We will use subtraction to find the area between two z-scores. Therefore, the area to the right of z = 1.53 is. By simple subtraction from 1, or 100%, we have To find the area to the right, we first find the area to the left of the z-score, then we subtract that area from 1. The white area is the area to the left of 1.53. That’s represented by the shaded area below. Let’s change the problem and find the area to the right of 1.53. In our first example, the area found to the left of z = 1.53 was. In this picture, 100% of the bell curve is shaded.

For any z-score, the area to its right plus the area to its left must equal 1, or 100%. To find the area to the right of a z-score, first understand that the bell curve has 100% of area beneath it in total. So, 22.36% of area is to the left of z = -.76. Then, go to the row with 0.7, and go to the column. 76 into two parts, the first is -0.7, and the second is. To find the area to the left of z = -.76, first, break up the number –. Since this shaded area is less than 50% of the bell curve, the area we get as an answer will be less than 0.5. Using the negative z-table, we will find the area to the left of z = -.76.

The vertical line dividing the black shaded region from the white un-shaded region is z =-.76. The area under the normal curve to the left of z = -.76 would be graphically represented like this: Suppose that a problem gives you a z-score of -.76, and you need to find the area to its left. 5000, that’s the same area we found for a z-score of 0.00. You’ll find the area for -0.00 in the last row of the first area column. A z-score of -0.00 is the same as a z-score of 0.00. Notice that all the values for z in the first column are negative.

Here is a full picture of the negative z-table.

How to Use the Z-Table for Negative Z-Scores So, 93.70% of area is to the left of z = 1.53. Then, go to the row with 1.5, and go to the column. To find the area to the left of z = 1.53, first, break up the number 1.53 into two parts, the first is 1.5, and the second is. The z-table has areas expressed as decimals rounded to 4 places, not percents. Since this shaded area is more than 50% of the bell curve, the area we get as an answer will be more than 0.5. Using the z-table, we will find the area to the left of z = 1.53. The vertical line dividing the black shaded region from the white un-shaded region is z = 1.53. The area under the normal curve to the left of z = 1.53 would be graphically represented like this: Suppose that a problem gives you a z-score of 1.53, and you need to find the area to its left. This should make sense, since a z-score of 0.00 is exactly in the center of the bell curve, with exactly 50% of the area to its left. Therefore, a z-score of 0.00 has an area to its left of. Next, we put these two values together, and we have a z-score of 0.00. Note that the number in the column header for. Note that the z-score is 0.0 in the first column, first row. The z-table shows areas as 4 digit decimal values throughout the rows and columns. Notice that all the values for z in the first column are positive. Here is a full picture of the positive z-table. How to Use the Z-Table for Positive Z-Scores Even better, try the fantastic Normal CDF calculator here! But, if you are using a z-table, read on. You may have a calculator with a normal cumulative distribution function (normalCDF) like the TI 84. Some teachers require students to use z-tables, but there are other ways to find area under the normal curve. And finally, I’ll guide you through finding area given z-scores.

Using some simple subtraction, you can also find the area to the right of a z-score, or the area between z-scores with the z-table. The z-table is a chart of numbers that we use to identify the area under the normal curve to the left of a z-score. In this article, I’ll walk you through how to use the z-table, or z-score table.
