Graphing and Analyzing Data
In virtualobservatory.org projects or in your own studies, you will often
need to make graphs or calculations with data. This site
can't directly analyze data, so you will need to use a
graphing program.
In this brief tutorial, you will learn many of the
skills required to make graphs and calculations with astronomical
data. The tutorial uses Excel, a spreadsheet program
published by Microsoft. We chose to use Excel because it is a
commonly used, relatively simple program that can graph and analyze many
different types of data.
If you use a plotting program other than Excel, you would
follow similar steps to graph and calculate with data. However, the
specific steps you would follow would be different. Consult your
user's manual for the software you use.
