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 calculator computes data for both the one-sample Z-test and the two-sample Z-test. It also provides diagrams to visualize the results.
This tool helps you perform a one-sample Z test for hypothesis testing quickly and accurately. our calculator simplifies the process of determining p-values, critical value, test statistics, decision and Conclusion.
Use a z-table to find probabilities corresponding to ranges of z-scores and to find p-values for z-tests. The z-table is divided into two sections, negative and positive z-scores. Negative z-scores are below the mean, while positive z-scores are above the mean.
