To calculate the Z test statistic: Compute the arithmetic mean of your sample. From this mean subtract the mean postulated in null hypothesis. Multiply by the square root of size sample. Divide by the population standard deviation. That's it, you've just computed the Z test statistic!

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.
The critical value calculator is an easy-to-use tool for determining critical value whether it is a one-tailed test or two-tailed test. Test type : in this fields enter the type of test from z-score, t-score, chi-square \( \chi^2 \), F-score or correlation coefficient r.
This Z-test calculator computes data for both one-sample and two-sample Z-tests. It also provides a diagram to show the position of the Z-score and the acceptance/rejection regions.
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. A table of Z scores and corresponding p-values is included, as well as the z score formula.
