In my data mining course, we are working with a data set. I have to identity the ranges of each attribute. I am given the set of data for all 150 points and i am given the visualization (charts) of all attributes. However I do not know how to use that set of data or the charts to find the ranges of each attribute. I do not know what is meant by range either.
I'm working on the data set for Iris plants and I have three classes of the flower.
