Asked by Tiffany

the estimate and uncertainty for experiment 1 is .15+-.01 and the .12+-.01 for experiment 2. Is the discrepancy between these two data sets significant? Why?
Answered by drwls
I would say yes, the discrepancy is probably significant, because the measurements should agree to within less than three standard deviations if they were measuring the same thing. These measurements differ by three standard deviations.

can you explain what you mean by three standard deviations? thanks
