Sample Tabular Data: Fisher Iris

Source Notebook

Fisher's iris tabular data

Details

The data set consists of 50 samples from each of three species of iris flowers: setosa, versicolor, virginica. Four features were measured from each sample: sepal length and width, petal length and width.

Scope & Additional Elements (1) 

Compute the mean of each measurement for each species variety:
In[5]:=
AggregateRows[ResourceData[\!\(\* TagBox["\"\<Sample Tabular Data: Fisher Iris\>\"", #& , BoxID -> "ResourceTag-Sample Tabular Data: Fisher Iris-Input", AutoDelete->True]\)], {"SepalLengthMean" -> Function[Mean[#SepalLength]], "SepalWidthMean" -> Function[Mean[#SepalWidth]], "PetalLengthMean" -> Function[Mean[#PetalLength]], "PetalWidthMean" -> Function[Mean[#PetalWidth]]}, "Species"]
Out[5]=

Visualizations (1) 

Plot sepal width vs sepal length for each iris species:

In[6]:=
iris2 = PivotToColumns[ResourceData[\!\(\* TagBox["\"\<Sample Tabular Data: Fisher Iris\>\"", #& , BoxID -> "ResourceTag-Sample Tabular Data: Fisher Iris-Input", AutoDelete->True]\)], "Species" -> {"SepalLength", "SepalWidth"}]; ListPlot[ iris2 -> {{ExtendedKey["SepalLength", "setosa"], ExtendedKey["SepalWidth", "setosa"]}, {ExtendedKey["SepalLength", "versicolor"], ExtendedKey["SepalWidth", "versicolor"]}, {ExtendedKey[ "SepalLength", "virginica"], ExtendedKey["SepalWidth", "virginica"]}}, AxesLabel -> {"SepalLength", "SepalWidth"}, PlotLegends -> {"setosa", "versicolor", "virginica"}]
