The error part of my physics labs have been takin up a lot of time lately. Anyways, say I have 10 numbers for time measurements like 3.53 s, 5.32 s, 3.57 s, 4.89 s, 3.24 s, etc...
and my reaction time is say +/- 0.20 s. I want to average these 10 values out but I have to associate an error reading like with the final value so for example my final value would like like : avg time = 3.23 +/- 0.13 s.
ok to rephrase it, say I find my standard deviation to be 0.08947 using Excel. My reaction time is 0.20 s and my average value is 1.41 s. How would I incorporate/propogate the rxn time and stnd deviation to find the final +/- error value?
