Star plots are a form of graphical data analysis which examins the behavior of all variables in a multivariate set. Each "star" displayed can represent a single measured observation. The spokes in star plots represents a unique variable in the data set. Where the data points meet on the spoke determine to measured data's value. They use a specified subset of data to examine the behavior of variables. The above example compares different car brands and models with specified variables. These range from price to length. The spokes are numbered correlating to a specific data set, ie, "1" is the price and "9" is the length. The longer the intersection point on the spoke the more expensive the vehicle is when looking at spoke "1" and longer if the length of intersection on spoke "9" is greater. This star plot is comparing 7 different characteristics between various makes and models of automobiles.
