Z Test Calculator is a free online tool that displays the Z score for the given data values. StudySolver online Z test calculator tool makes the calculation faster and it displays the Z static or Z score value in a fraction of seconds.

The procedure to use the Z test calculator is as follows:

Step 1: Enter the data values separated by a comma and the standardized random variable in the input field

Step 2: Now click the button ”Calculate Z score” to get the result

Step 3: Finally, the Z score or the Z static value for the given data values will be displayed in the output field

In Statistics, Z test is a hypothesis testing which follows the normal distribution. The Z test is used to determine whether the population means are different from each other when the variance values are known and the sample size is relatively large. The Z-score or the Z static represents the number, which is the result of the Z test. In hypothesis testing, the Z test and T-test are closely related to each other, but T-test will produce a better result when the sample size is small in the experiment.
