Iris DatasetThe Iris flower data set or Fisher's Iris data set isa multivariate data set introduced by the Britishstatistician and biologist Ronald Fisher in his1936 paper The use of multiple measurementsin taxonomic problems as an example of lineardiscriminant analysis.The data set consists of 50 samples from each ofthree species of Iris (Iris setosa, Iris virginica andIris versicolor). Four features were measuredfrom each sample: the length and the width of thesepals and petals, in centimetres. Based on thecombination of these four features, Fisherdeveloped a linear discriminant model todistinguish the species from each other.
