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.
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.
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.
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.

5 lis 2020 · The standard normal distribution, also called the z-distribution, is a special normal distribution where the mean is 0 and the standard deviation is 1. Any normal distribution can be standardized by converting its values into z scores.
