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.
Let x represent the data value, mu represent the mean, sigma represent the standard deviation, and z represent the z-score. Since the z-score is the number of standard deviations above the mean, z = (x - mu)/sigma. Solving for the data value, x, gives the formula x = z*sigma + mu.
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
The Z-score Calculator is an online tool to measure how many standard deviations an element is from the mean. It efficiently aids in statistical analysis by making complex calculations straightforward and accessible.

7 cze 2024 · A z-score table helps you find the p-value, or percentile, your data point corresponds to based on its z-score. Follow these steps: Determine if your z-score is negative or positive. If the z-score is negative (i.e., the data point is less than the mean), use a negative z-score table.
