Star Plot

A star plot is a method of displaying multivariate data. Each star represents a single observation. They are used to examine the relative values for a single data point and to locate similar or dissimilar points. This plot is an automobile analysis (1979), and it shows similarities and differences between car features, like gas milage and trunk space.

Correlation Matrix

A correlation matrix lists the variable names down the first column and across the first row. The diagonal of a correlation matrix (the numbers that go from the upper left to the lower right) always consist of ones. That is because these are the correlations between each variable and itself (and a variable is always perfectly correlated with itself).
