This is a data set with measurements of Irises made famous by Sir Ronald Fisher

There are three species of Iris: 1= SETOSA, 2=VERSICOLOR, and 3=VIRGINICA.

There are four measurements on each of the flowers: Sepal Length, Sepal Width, Petal Length and 
Petal Width.  All measurements are in millimeters.

Do the measurements differ by species?  Can the measurements be used to predict the species of 
the iris?

Look at plots of the data and possibly analyses of the data to characterize differences between 
the three species based on these four measurements.
