F-Test Calculator (for Two Variances)
This calculator is designed for statisticians and data analysts to compare two variances using the F-Test. It helps determine if the differences between two data sets are significant.
F-Statistic:
0.00
Data Source and Methodology
All calculations are rigorously based on the formulas and data provided by authoritative sources in the field of statistics.
The Formula Explained
F = \(\frac{\text{Variance 1}}{\text{Variance 2}}\)
Glossary of Terms
- Variance 1: The variance of the first data set.
- Variance 2: The variance of the second data set.
- F-Statistic: The ratio of the two variances used in the F-Test.
How It Works: A Step-by-Step Example
Consider two data sets with variances of 4.5 and 3.0. The F-Statistic is calculated as follows:
F = \(\frac{4.5}{3.0} = 1.5\)
Frequently Asked Questions (FAQ)
What is an F-Test?
An F-Test is used to determine if there are differences between the variances of two populations.
How do you find F-statistic?
The F-statistic is calculated by dividing the variance of the first group by the variance of the second group.
