Answer 1

@amistre64 @kropot72 @jtvatsim @sdfgsdfgs

Answer 2

depends on the course

Answer 3

AP Statistics

Answer 4

its not standardized. i meant its specific to your course. it should be in your material.

i can take a guess at it but it would in no manner be considered correct

Answer 5

given a data set in (x) we have 1 degree of freedom its 1 dimensional

by extension, (x,y) is 2 dimensional

Answer 6

Yeah... my lessons in my course are terrible and in this one the link is a video that is no longer working so I have been winging it off of stattrek.com

Answer 7

I found (n-2)

Answer 8

the side effects of having a democrat in office ....

Answer 9

in some courses its (x-1) + (y-1) or (x+y) - 2

in other courses its the smaller of x or y, -1

Answer 10

in others they take an average of x and y

Answer 11

ok. Yeah, it's a little frustrating

Answer 12

in others theres a more complicate formula ... its course dependant

Answer 13

ok. Well, thank you for taking a look at it and trying :)

Answer 14

if the ordered pairs are independant, one does not effect the other, then i would conclude that we have 2 degrees of freedom

but if x affects the choice for y, then we only have one degree of freedom ...

say x + y = 6

we are free to choose x, say 2. but the value of x doesnt give us any freedom to choose y now, y has to be 4

if we have a function of 2 independant variables, f(x,y) then we are free to choose x and y, 2 degrees of freedom

but if y = g(x) the f(x,g(x)) only really has 1 degree of freesom

how this relates to your question tho is beyond me
