Let us understand how to calculate the Z-score, the Z-Score Formula and use the Z-table with a simple real life example. Q: 300 college student’s exam scores are tallied at the end of the semester.

Find the percentage of values below a given z-score in a standard normal distribution.

Use this z table, also referred as z score table, standard normal distribution table and z value chart, to find a z score.

A z-score table, also called a standard normal table, shows the cumulative probability associated with each z-score in a standard normal distribution (mean = 0, standard deviation = 1).

STANDARD NORMAL DISTRIBUTION: Table Values Represent AREA to the LEFT of the Z score. -3.9 -3.8 -3.7 -3.6 -3.5 . -3.4 -3.3 -3.2 -3.1 -3.0 . -2.9 -2.8 -2.7 -2.6 -2.5 . -2.4 -2.3 -2.2 -2.1 -2.0 . -1.9 -1.8 …

Sep 16, 2025 · In this guide, you’ll learn what the z score table is, how to read it, and how to use both positive and negative z tables with simple examples. What is a Z Score Table?

This interactive Z table displays probabilities (areas) under the standard normal distribution curve for specific z-scores. It helps determine the probability of values falling within particular ranges in …

Row and column headers define the z-score while table cells represent the area. Learn how to use this z-score table to find probabilities, percentiles, and critical values using the information, examples, …

The Z-table contains the probabilities that the random value will be less than the Z score, assuming standard normal distribution. The Z score is the sum of the left column and the upper row.

4 days ago · Using the formula for Z-Score. The z-score table is divided into two sections: The negative z-scores are below the mean, while the positive z-scores are above the mean. The rows and …
