The difference between two variances
Applied to focusing lenses and mirrors, including telescopes, binoculars, and cameras, the focal ratio or 'F-number' is (the focal length of the lens or mirror) divided by (its aperture or diameter)
The F-test is designed to test if two population variances are equal. It compares the ratio of two variances. If the variances are equal, the ratio of the variances will be 1.The F-test provides the basis for ANOVA which can compare two or more groups.One-way (or one-factor) ANOVA: Tests the hypothesis that means from two or more samples are equal.Two-way (or two-factor) ANOVA: Simultaneously tests the hypothesis that the means of two variables from two or more groups are equal.
A F-ratio test compares 2 variances and tell if they are significantly different. A Chi-square test compares count data.
An F in statistics is typically a grade. This F means that you are failing or have failed the course.
odds ratio.
Ratio level of measurement is the highest in statistics.
The effect of low signal-to-noiseratio on the ratio statistics constitutes the main theme of the paper. Finally, and in this vein, a quality metric is ...
An F-statistic is a measure that is calculated from a sample. It is a ratio of two lots of sums of squares of Normal variates. The sampling distribution of this ratio follows the F distribution. The F-statistic is used to test whether the variances of two samples, or a sample and population, are the same. It is also used in the analysis of variance (ANOVA) to determine what proportion of the variance can be "explained" by regression.

In Argentina the statistics solve to a ratio of approximately 95.7 men per 100 women
Level of measurement most inferential statistics rely upon is ratio.
