Physics paper 33 messed up real bad

[Scafalon40]

Guys two of my x values yielded the same y value leading to two extremely anomalous points. I didn't include those in my line of best fit, but I need some cheering up
I checked their respective readings over and over again: the calculated values wouldn't change
Really sad

What was your gradient? I got -3 which is apperantly wrong.

 

[Badr]

Got my gradient negative 3.8..... And my Y intercept was 10.23 is that correct? Teacher said the gradient is something between 0.02 and 0.03

Gradient=0.125
Y intercept=don't ask

 

[Sarmad Furqan]

my gradient was -0.05....anybody else had it in paper?

what you people wrote in the part in which we have to make a comparison between two values of k...what was your percentage error..did you approve the relation? the paper really was difficult..mainly the graph i don't know why i'd much problem in practicals.. what is the threshold gonna be for this paper??

my k values wer almost da same so my % error was 2.3%... so da relationship proved ryt for me... evn i didnt like da graph qustion it was horrible..

oh yes...same was the case with me abdullah...

 

[Sarmad Furqan]

my %age error was 12.58 % and i also proved the relation..

 

[fathimaash]

my %age error was 12.58 % and i also proved the relation..

oh really dats great

35% error ..gradint also wrng n so is ma y intrcpt!!

 

[Sarmad Furqan]

35% error ..gradint also wrng n so is ma y intrcpt!!

same is the case with me in question 1 ...i did some blunders..really cursing myself..

 

[oldfashionedgirl]

well, first of all, a value of gradient is NOT fixed so stop worrying....in phy practicals u mainly get marks for small details, like the number of significant figures used, graph plotted,line of best fit and mostly, the WAY u solved the paper. In mark schemes as well u'll notice that they rarely, if ever, give the values for gradient. Dunno what everyone here is stressing about

btw, my relation did not hold true

 

[mujtabashahnawaz]

38% error here

 

[thunderingthunder]

Q1 to was bad
Q2 went gud

 

[JD REBORN]

38% error here

What was ur absolute uncertainty?

 

[arkif rizan]

i got a negative gradient which was -0.12 and intercept which was 1.0 but every 1 else they got +ve gradient

 

[Scafalon40]

And just like that everyone forgot the purpose of the thread...
Thanks guys, you're the best!

Line of best fit doesn't include all the points any way
Secondly u can get ecf...for ur line and gradient and everything that follows...relax it shud be fine (Y)

Thanks dude, that helps.
By the way I think you misunderstood something: I could only consider three points, and so I included them only.
