Calculate z-scores and probabilities for normal distributions using this online tool. Find z-scores for raw scores, mean and standard deviation, or two z-scores, and refer to z-tables for standard normal values.
Find the Z-score, P-value, and probability for any test value, mean, and standard deviation. Use the negative Z table to look up the Z-score for a given P-value or probability.
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.
Press the 'Calculate' button to obtain the z-score for a normal distribution. When you select the row score method, the tool returns the probabilities (left-tailed, right-tailed, two-tailed) along with the z-score.
Calculate Z scores and p-values from raw scores, mean and standard deviation using the standard normal distribution. Find Z table values, formula, examples and applications in statistics and probability.
Calculate the z-score for a raw score value, a population mean, and a population standard deviation using this online tool. Learn the formula, see the results, and find examples of z-score calculation.
Z-Score Calculator can be used for any type of Z-Score-related calculations. You can enter a raw score (X), Population mean ( μ), and Standard Deviation (σ) in the first calculator to find the Z-Score with steps and related probabilities to that row score.
