F distribution

how to get value for F(16,19)?

 

can someone plz type in the calculations.

 

Let,
F(12,19)=a and F(24,19)=b
You need F(16,19)
So by interpolation, F(16,19)=a + [(16-12)/(24-12)]*(b-a)

 

thanks

 

That is useful.
also please help to find F( 15,15)
with general formula.

 

General formula! you meant find it by integrating PDF , it will take more time than worth.

If you wanna find it by table, then
Let,
F(12,15)=a and F(24,15)=b
You need F(15,15)
So by interpolation, F(15,15)=a + [(15-12)/(24-12)]*(b-a)
