Experimental testing and Curve fitting

Experimental testing and curve fitting

Once data have been collected from an experiment, it is often useful to present them in graphical form. This can be done by using a calculator but, if a computer is available, it can also be done by the spreadsheet package Excel.

Charles Babbage (1792-1871) English mathematician and inventor. Worked on an analytical engine to be programmed to perform a sequence of arithmetical operations. Pioneer of the computer.

This module explains how to graph data in Excel, how to fit curves to these graphs and how to customise these curves to reflect the experiment being analysed. It also shows how trendlines can be added and interpreted and how two sets of data can be handled. Finally it illustrates how errors in physical calculations can be represented in Excel through the use of error bars.
