The F-distribution is the distribution of the ratio of two independent χ

So, if u & v are independently χ

**DEfinition**:The F-distribution is the distribution of the ratio of two independent χ

^{2 }random variables divided by their respective degrees of freedom (df).So, if u & v are independently χ

^{2 }variates with m & n respectively, then we are interested to find the distribution of the quantity.
This is also called variance ratio.

**Application of F-distribution:**

1. To test the equality of several mean

2. To test the linearity of regression

3. To test the significance of simple correlation ratio, η
