AI Thread Summary
The discussion centers on determining the accepted error margin when using a handheld stopwatch for timing experiments. Participants acknowledge that while the stopwatch can measure to 0.01 seconds, human reaction time introduces a greater error, with suggestions around +/- 0.1 seconds being reasonable. There is recognition of individual variability in reaction times, which complicates establishing a standard error. A reference to a Wikipedia article on reaction time is provided for further insights. Understanding these factors is crucial for accurate timing in experimental settings.

Homework Statement



I'm not too sure if this is the correct forum, but I had an experiment where we were timing things with a hand held stopwatch. The stopwatch goes to 0.01 seconds, but clearly the human error would outweigh that error.

So, if anyone could help me, I would like to know what the 'accepted' error in pushing a stopwatch would be.

Yes, I know we all have different reaction times, but I was thinking along the lines of +/- 0.1 seconds?

Thanks

Physics news on Phys.org
half of that
try clicking it twice voluntarily and you know the error
neurons shoot at ahigh speed ,almost the same as on witnessing an event

Wow, the wikipedia article has lots of stuff in it! Yoiks.

Anyway, you may be able to find good into to use in the article. You can even reference it in you lab report:
