F-Test Calculator is a free online tool that displays the mean, variance and frequency distribution value for the given data set. BYJU’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 – Variance1/Variance2
Variance1 = variance of the first data set
Variance2 = Variance of the second data set
