This Z-test calculator is a tool that helps you perform a one-sample Z-test on the population's mean. Two forms of this test - a two-tailed Z-test and a one-tailed Z-tests - exist, and can be used depending on your needs. You can also choose whether the calculator should determin...

P Value from Z Score CalculatorThis is very easy: just stick your Z score in the box marked Z score, select your significance level and whether you're testing a one or two-tailed hypothesis (if you're not sure, go with the defaults), then press the button!
The sample size calculator computes the sample size to gain the required test power and draws a power analysis chart.You should calculate the sample size before performing the research.Use this test for one of the following tests: For One Sample Z-Test choose the following:Distribution: Normal....
To use this calculator, just input your population mean, population variance, sample mean and the number of individuals in the sample into the text boxes below. You also need to select a significance level and whether your hypothesis is one or two-tailed. Hit the calculate button (below) whe...
Z critical value calculator, uses a significance level value and test (left-tailed, right-tailed, two-tailed) to calculate z-critical value for the standard normal distribution N(0,1), or close to normal distribution
This calculator conducts a Z-test for one population mean µ, with known population standard deviation σ. Please select the null and alternative hypotheses, type the hypothesized mean, the significance level, the sample mean, the population standard d
Calculator What is the Z Test Statistics Formula? Z Test statistics is a statistical procedure used to test an alternative hypothesis against the null hypothesis. It is any statistical hypothesis used to determine whether two samples means are different when variances are known and the sample is la...
The p-value calculator calculates the p-value for Z score, T score, F score and Chi-square score.If you don't have the score you may use one of the following calculators that will compute the score and the p-value:One sample Z-test, Two sample Z-test, One sample T-test,Two-Sampl...
