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.

Find the percentage of values below a given z-score in a standard normal distribution.

Use this z table, also referred as z score table, standard normal distribution table and z value chart, to find a z score.

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.

Nov 4, 2025 · Z-score calculator computes a standardized z-score for any raw data point x. Enter population mean and standard deviation for a given normal distribution.

This page has two interactive Z-score calculators. The first calculator computes a Z-score based on your observed value, the mean, and the standard deviation. The second uses a Z-score to …

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 …

Calculate Z-scores, p-values, and confidence intervals with our easy-to-use statistical calculator.

Enter the three factors (population mean, standard deviation, and raw score) into the calculator and it will generate the appropriate Z-Score. This standard score identifies where your raw …
