Title: Error Bars of Uncertainties..Urgent..Exam in less than 24 hours!
Post by: Meticulous on May 18, 2010, 02:32:49 am

Can anyone please tell me how to find the uncertainty using error bars? Drawing 3 lines of best fits?

It's really urgent. Needed ASAP

Thanks in advance.

Uncertainties can be calculated from graphs. I just want to know the method.
