The best resource is the internet or the university research library. Instead of looking up box and whisper plots and steam and leaf diagrams as keywords
on the internet, I'll cut the searching time for the students by telling them
(as they might know from their text(s)) that the inventors of several of these
plots were Professors Mosteller and Tukey of Princeton and Harvard universities. As for their own texts, if the texts do not analyze but only teach drawing, I would recommend considering changing the textbook peer review committees.
