    Error Analysis:

This is a short discussion on error analysis. It, along with subsequent lecture notes, will provide information on how to analyze your data.  There are excellent discussions of expressing uncertainty by NIST as well as on statistics and probability from LBL.  There are no course textbooks, but we recommend buying or checking out of the library An Introduction to Error Analysis by Taylor and/or (for in-depth information on error analysis) Data Reduction and Error Analysis for the Physical Sciences by Bevington and Robinson.
