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.
The Z Score Formula or the Standard Score Formula is given as. When we do not have a pre-provided Z Score supplied to us, we will use the above formula to calculate the Z Score using the other data available like the observed value, mean of the sample and the standard deviation.
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.

30 cze 2024 · What is the standard normal distribution? You can standardize any normal distribution, which is done by a process known as the standard score. This is when you subtract the population mean from the data score and divide this difference by the population's standard deviation. A standard normal distribution has the following properties:
