I really don't understand how to calculate this. I'll give you an example, so that maybe you can help me with it. I just need a formula or a sample of how to do it or something.
Four consecutive measurements of a sample of lithium sulfide give the values of 3.45g, 3.44g, 3.44g, and 3.43g. What are the absolute deviations of each measurement and how should you express the final answer to indicate the precision of you answer?
My teacher said the formula for it was...
Absolute deviation=absolute difference between each measurement and the average
I don't really know what he meant by this. (absolute difference between each measurement?)
The answer is 3.44g +/- .005g
