SOCR Data - Fisher's multivariate dataset on iris sepal and petal length
Data Description
These data were acquired for and used by R.A. Fisher to study the use of multiple measurements in taxonomic problems.
These data are commonly used in the pattern recognition and multivariate data analyses. The data set contains 3 classes (Iris types) each containing 50 observations (for a total of 150 observations). One class is linearly separable from the other two, but the latter are difficult to linearly separable from each other. The class of the iris plant may be used as the predicted variable. There are 4 variables which can be used as predictive (explanatory) attributes of the Iris class.
