F-Test Calculator is a free online tool that displays the mean, variance and frequency distribution value for the given data set. CoolGyan’S online F-test calculator tool makes the calculation faster, and also it displays the F value in a fraction of seconds.

## How to Use the F-Test Calculator?

The procedure to use the F-Test calculator is as follows:

**Step 1:** Enter the set of data values separated by a comma in the input field

**Step 2:** Now click the button “Calculate” to get the frequency value

**Step 3:** Finally, the mean, variance and the F-value will be displayed in the output field

### What is Meant by F-Test?

In Statistics, F-test is a statistical test that uses the frequency distribution. To calculate the F-value or the frequency value, the test compares the variances for the given two data values. In the F-test, the test static has a Frequency distribution (F-distribution) under the null hypothesis. Before, finding the variance of the data set values, find the mean value for the given data set. Thus, the formula to calculate f-value is given by

F-value – Variance_{1}/Variance_{2}

Variance_{1} = variance of the first data set

Variance_{2} = Variance of the second data set
