dumbcow · Answer

is this for a stats class?
are you doing a linear regression?

lila · Answer

yes this is stat

dumbcow · Answer

ok first find correlation by using mean and std deviation of each x and y
r =1/4*sum(((xi-xmean)/sx)((yi-ymean)/sy))

lila · Answer

i have no clue how that works lolz

dumbcow · Answer

then find least squares regression line
y = b1x+b0
b1 = r(sy/sx)
b0 = ymean - b1*xmean

dumbcow · Answer

lol ok maybe try this then
plot the points and see if the line looks linear, quadratic, or exponential

lila · Answer

lol math is nt my subject i just have to take it
