Using the F Table to Find Areas and Percentiles

I show how to find percentiles and areas for the F distribution using the F table. In the first part of the video I work through examples finding areas and percentiles in the right tail of the distribution. (These are often of more importance to us than the left tail values.) In the second part of the video I show the mathematical "trick" that allows us to find left tail values from a table that gives only right tail values, and work through examples.

Thanks Joe! You are very welcome.

The other type of F table has one tail area per page (for example, a = 0.10 on one page, a = 0.05 on another). That's not the format I prefer. For that type, you'd use the same logic, but you have to flip between the pages. I think the table format given here is better for a number of reasons, so it's the one I use.

can you help me to get the F value for a VECM of 45 observations and 3 variables... i think it should be a (3,42) ?... 2,82 ??

at :56, would this be the correct way in R to get the exact value for P(F>2.448): > df(2.448, df1=3, df2=14)

[@jbstatistics]

1-pf(2.448,3,14) would do it.

[@MnemoSemiotic]

awesome, thank you for the quick response, teaching myself R

why are most tables not like that? for example the first one in google
how would i use this table?

[@anjalilakra15]

which table is this ? i use devore tables

[@engamnaali]

where can i have a table like yours ?

[@BlowMeBG]

u made a mistake at 5:57
df=5 is denominator, not numerator. Right?

[@dam1ans317]

Nope u flipped for the property :)

[@JRxzzle9]

Ok thanks, helpful video

Sorry to say that the area we have worked out is less than .10 and greater than .025
