    FREQUENCIES: Choose number of bins for histogram based on valid cases.
    
    Until now, histograms have always had exactly 11 bins.  There is no
    "correct" number of bins, but a fixed number of bins also seems less than
    ideal.  Use Sturges' formula, instead, to choose the number of bins.
