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.

How would I use Microsoft Excel to find that final error value? I know that I could find the standard deviation but that takes forever on paper, and what/how exactly would I propgate it with my reaction time?

2. Relevant equations

I think you'd have to use those statistics forumlas on Excel
