Significant Figures Tutorial


Excel Tutorials & Examples 

Getting Started with Excel

Graphing with Excel (includes information about trendlines and error bars)

How to do a Linear Regression with Excel (Excel's regression tool gives you the uncertainties on the slope & y-intercept)

Weighted Least Squares example (the proper way to do a linear regression when the uncertainties on the y values are not all the same)

Solver example (Solver is useful for doing nonlinear regressions)

MacroBundle   Robert de Levie's free collection of ready-to-use Excel macros.  Very useful for laboratory data analysis.  A description of each macro as well as instructions for installing Macrobundle in Excel may be found at the beginning of the document.
