IRIS Flower Data Set

• A multivariate data set introduced by Sir Ronald Fisher (1936) as an example of discriminant analysis.

• The data set consists of 50 samples from each of three species of Iris:

  1. Iris setosa
  2. Iris virginica
  3. Iris versicolor
  

• Four features were measured (in cm) from each sample:

  - Sepal length and width
  - Petal length and width
  

• In this slidify deck we present exploratory data analysis with this data set.
