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....
If you need to derive a Z score from raw data,you can find a Z test calculator here. Z score: Significance Level: 0.01 0.05 0.10 One-tailed or two-tailed hypothesis?: One-tailed Two-tailed Enter your z score value, and then press the button. ...
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
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
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...

To find the critical value for a Z test, you need to know the significance level and whether it is one- or two-tailed. Learn more aboutCritical Values: Definition, Finding & Calculator. Z Test Worked Example Let’s close this post by calculating the results for a Z test by hand!
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...
For a symmetric distribution, finding critical values for a two-tailed test with a significance of \(\alpha\) is the same as finding one-tailed critical values for a significance of \(\alpha/2\). Alternatively to using this calculator, you can use a z critical value table to find the ...
