hey,
can someone help me how to draw the error bars in summer 09 physics paper 5, q 2. ive found the error in the readings, but the errors are so tiny, you cant even see the error bars. or am i doing something really wrong.
Thanks

I got my error values as : 0.017, 0.012, 0.009, 0.008, 0.007 ... is that what you got?

so the error bars would be a bar from (lgI - error) up to (lgI + error)
Only the last error bar for 0.806 (lgI value) should be very small.. it goes from 0.799 to 0.813.
Make sense??

winnie101:
oops found my mistake.
Thanks
