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. In the above example, we derive that Eric's Z-score is 0.56. Once you have the Z Score, the next step is choosing between the two tables.
The z-score table is divided into two sections: negative z-scores and positive z-scores. The negative z-scores are below the mean, while the positive z-scores are above the mean. The rows and columns of the table define the z-score, and the table cells represent the area.
Step 1: Find the z-score. First, we will find the z-score associated with a height of 26 inches. z-score = (x - μ) / σ = (26 - 26.5) / 2.5 = -0.5 / 2.5 = -0.2. Step 2: Use the z-table to find the percentage that corresponds to the z-score. Next, we will look up the value -0.2 in the z-table:
The z-scores to the right of the mean are positive and the z-scores to the left of the mean are negative. If you look up the score in the z-table , you can tell what percentage of the population is above or below your score.

Suppose you want to find the probability of a Z-score of -2.25 or lower. Step 1: Identify the Z-score as -2.25. Step 2: You are looking for the probability to the left of the Z-score. Step 3: Use the negative Z-table. Step 4: Find the intersection of the row for 2.2 and the column for 0.05. The value is 0.0122.

Use this Z table calculator to easily calculate the Z-score from a given raw score. Also computes areas under the normal curve ( p -values) cut off by a given score. A table of Z scores and corresponding p-values is included, as well as the z score formula. Also calculates Z from p. Calculate Quick navigation: Using the Z score calculator
