Use the positive Z score table below to find values on the right of the mean as can be seen in the graph alongside. Corresponding values which are greater than the mean are marked with a positive score in the z-table and respresent the area under the bell curve to the left of z.

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. What is z-score?
A z-table, also called standard normal table, is a table used to find the percentage of values below a given z-score in a standard normal distribution. A z-score, also known as standard score, indicates how many standard deviations away a data point is above (or below) the mean.
Use a z-table to find probabilities corresponding to ranges of z-scores and to find p-values for z-tests. The z-table is divided into two sections, negative and positive z-scores. Negative z-scores are below the mean, while positive z-scores are above the mean.
20 kwi 2020 · A z-table is a table that tells you what percentage of values fall below a certain z-score in a standard normal distribution. A z-score simply tells you how many standard deviations away an individual data value falls from the mean. It is calculated as: z-score = (x – μ) / σ. where: x: individual data value; μ: population mean
6 paź 2023 · A Z-score table, also called the standard normal table, or z-score chart, is a mathematical table that allows us to know the percentage of values below (usually a decimal figure) to the left of a given Z-score on a standard normal distribution (SND).
14 mar 2024 · To use a z-table, first turn your data into a normal distribution and calculate the z-score for a given value. Then, find the matching z-score on the left side of the z-table and align it with the z-score at the top of the z-table. The result gives you the probability.
