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.
Z score calculator to calculate a Z score from a raw score. p-value from a Z score or Z score from probability. Z statistic calculator with support for normal distributions with custom mean and sigma. Z score formula and explanation with examples, as well as a Z table with key values. Free online Z table calculator.
Z-score, otherwise known as the standard score, is the number of standard deviations by which a data point is above the mean. You can use our z-score calculator to determine this value for you. Read on to learn how to calculate the z-score and how to use the z-score table.
You can use this Z-Score Calculator to calculate the standard normal score (z-score) based on the raw score value, the population mean, and the standard deviation of the population. How to use the calculator. Enter the raw score value.
Compare observations between dissimilar variables. Identify outliers. Calculate probabilities and percentiles using the standard normal distribution. In this post, I cover all these uses for z-scores along with using z-tables, z-score calculators, and I show you how to do it all in Excel.
This calculator solves three types of problems related to z-scores. 1. Find the area (probability) to the left, right, or between two Z-scores. 2. Find the z-score if the cumulative probability level (p-value) is given. 3. Find the z-score based on the raw value, mean and standard deviation of a population.
The Z-Score Calculator helps to get the z-score of a normal distribution, convert between z-score and probability, and get the probability between 2 z-scores.
