# how to show percentage of uncertainty on a graph watch

1. Hi guys ,
simple question , i'm trying to spot a point with uncertainty of it on a graph but I'm not sure if my answer is correct. would appreciate any comment on a graph if the graph isn't correct thanks

2. Dammit use graph paper please xD
But really, looks fine. the range bars show the error correctly. I rarely see range bars on the x axis though.
if thats all you need, thats fine
Also plot the other points if you have any, and draw a line of best fit

Deffo will next time 😋
One last question, i want to calculate the mean value of gradient as well , should i draw the max and min gradient on the graph and then calculate the magnetude of them which will then devided by two two give me the mean value

Yes, calculate the minimum 'acceptable' and maximum 'acceptable' gradients
Add them together divide by 2 = Mean gradient for my course (OCR A)

Im not sure what course you are doing. Due to you saying practical and unit 6, are you doing EMPA?
If so, here is a good thread on this.
The previous EMPA threads are sure to be of use also.
Stress brings nothing but worries, unless you can control it. Dont stress!
Good Luck
