Creating Bins in Excel

BlueEyedDollface 

I do not know if your class involves historiography, but I wonder if there is some confusion of terms. (I see that historiography has a different Greek root than than the root for histogram.)

So far as I know, the use of bins in Excel is toward creating histograms. Some helpful material regarding bin creation might be found in this article: Histogram – The Ultimate Guide of Binning 

In Excel, data values might be aggregated by the use of formulas using the COUNTIFS function (with the upper and lower bounds of a bin as two criteria), and you can use a Bar Chart to display the histogram.  Or more easily, you can select your data, choose Histogram when inserting a chart, and let Excel calculate an appropriate bin size (you can change the bin width or number of bins under "Format Axis").
