Star Plot- a method used to examine relative values for a single data point.
A star plot has a sequence of spokes, with each spoke representing one variable. The data length of the spoke is proportionate to the magnitude of the variable. Star plots are often shown with multiple plots in one diagram, to compare observations. This diagram shows 16 star plots for different types of cars. The variables are: 1 price, 2 mileage (MPG), 3 1978 repair record (1= worst, 5= best), 4 1977 repair record (1= worst, 5= best), 5 headroom, 6 rear seat room, 7 trunk space, 8 weight, and 9 length.
