anyone got ERROR OF SLOPE? wat was ur value close to?

HEY IM HAVING ISSUES WITH MY ERROR OF X. ALL THROUGH THE EXCEL I'VE BEEN USING THE ERROR TO BE .003m, WHEN I GET TO THE BOTTOM CHART FOR X, I TRIED USING .003 AND ITS NOT WORKING. THEN I TRIED USING THE ERROR FORMULA AND IT DIDNT WORK EITHER. CAN SOMEONE PLZ HELP, BECAUSE I CANT CONTINUE WITHOUT FIND THE ERROR OF X. THANKS A LOT. [b]

anyone got ERROR OF SLOPE? wat was ur value close to?

WHAT IS THE ERROR IN X? Someone please post it

whats error of X

actuall in my case, my slope is 1.05E7, and I get error in slope is 2E5. my # turne into green. I hope it help!!!!!!!!!!

error of x is is sqrt((DeltaX^2 + DeltaX^2), since X is the twice the distance from the position to the middle.

we just simply put (sqrt(0.003^2+0.003^2)), assuming both errors are 0.003m

wavelength = 1/(Rh*((1/2^2)-(1/n^2)))
Rh is constant given in the instruction, 1.097E7

Can someone PLEASE tell me how to find X every way i try doesn't work, please help:(

for Delta X, we assume that each error is .003, when i enter in .004 (get that from sqrt(.oo3^2 + .003^2)) its marking me wrong. Does anyone know what i'm doing wrong? each error in X for the red,blue,purple is .003 right?

sqrt(0.003^2+0.003^2)

is 0.004243. Try to keep as many as digits possible.

It should work fine.

Anyone know how to calculate the error of the slope? or what number it should be around? thanks!

OKAY. I AM SOOOOO SORRY, I SWEAR I REALLY AM, I KNOW THERE HAVE BEEN NUMEROUS POSTS ABOUT THIS, BUT HONESTLY ITS NOT WORKING FOR ME AT ALL. I DID A COMBINATION OF THINGS, I WORKED OUT EQUATIONS, I PLUGGED IN, I DARN RIGHT EVEN DID A DANCE TO TRY TO GET THIS BUT ITS NOT WORKING.

I REALLY NEED HELP WITH THE ERROR OF X, IF I DONT GET THAT VALUE, I CANNOT MOVE ON TO GET THE OTHER ERROR VALUES.

I'VE BEEN USING .003m FOR MY ERROR, AND I USED THE ABOVE EQUATION sqrt((.003)^2+(.003)^2) to get .004243 etc... BUT WHEN I PLUG THAT INTO THE EXCEL ITS NOT WORKING. I PLUGGED IN .004, THEN I JUST PLUGGED IN THE WHOLE VALUE, THEN I JUST KEPT TRYING VARIATIONS, BUT NOTHING HAS WORKED. IT REALLY DOESNT MATTER HOW MANY DIGITS I PUT IN, BECAUSE WHEN I PUT IN THE WHOLE THING, IT DOESNT TURN GREEN. UGH.

CAN SOMEONE PLEASE TAKE THE TIME OUT FROM THIS GORGEOUS DAY TO HELP ME OUT. I REALLY APPRECIATE IT. THANKS.

how did u guys explain the observed sequence using eq 1?

finally found the error of x.

phygirl, what is it? because its not working for me either

how do you find the relative error in x/2y??? i'v got everything but the error of the slopes if someone will answer this for me.
