A Z Score is measured in terms of standard deviations from the mean. Which means that if Z Score = 1 then that value is one standard deviation from the mean. Whereas if Z Score = 0, it means the value is identical to the mean.

- Z TABLE
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.
Calculator to find out the z-score of a normal distribution, convert between z-score and probability, and find the probability between 2 z-scores.
The z-table is built based on the standard normal distribution. However, if you need to calculate the probability for a non-standard normal distribution, you can use the following z-score formula. Where: 𝑥 - the value. z - the z-score. μ - the mean. σ - the standard deviation. Example.
Z Tables are also called Standard Normal Table or Unit Normal Tables. Scroll down to see the Z table vaules. Interactive Normal Probability Distribution Graph with Z-score calculations
Input Data : Random Value (X) = 9.25. Mean (μ) = 9. Standard Deviation (σ) = 0.73. Objective : Find what is the normalized score of random member X? Formula : z-score = (x - μ) σ. Solution : z-score = (9.25 - 9) 0.73. = 0.25 0.73. z-score = 0.3425. p-value from Z-Table : From the table P (x < x1) = 0.6331. P (x > x1) = 1 - P (x < x1) = 1 - 0.6331.
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. Z score & P from raw score. Z score from P. Raw score.
