What is a Test Statistic Calculator?
A test statistic calculator helps to compute the test statistic value, which is used to assess the validity of a hypothesis. It’s an essential tool for researchers and statisticians.
How to Use Test Statistic Calculator
- Input the sample mean (x̄), population mean (μ), standard deviation (σ), and sample size (n).
- Click the “Calculate Test Statistic” button to get the result.
- The result is the test statistic value used to compare with critical values for hypothesis testing.
What is the Formula of Test Statistic?
The formula for calculating the test statistic is:
Test Statistic (Z) = (x̄ - μ) / (σ / √n)
