Fisher introducerede i 1936 et datasæt, som han havde indsamlet ved at måle bladstørrelserne på blomster af tre forskellige sorter. De tre blomstersorter tilhører alle iris familien og ligner hinanden meget. De latinske navne for de tre sorter er: Iris Setosa, Iris Virginica og Iris Versicolor. Irisblomsterne har to forskellige typer af blade: kronblade (petal) og bægerblade (sepal). Fisher målte bladenes længde og bredde og noterede disse for 50 eksemplarer af hver sort.`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":30,"value":"html`
