Finally we analyze and summarize our results as illustrated in columns G - J
In order to build our histogram we create the "Histogram Data" table. The
"# Scores" cells uses the CountIf() function to tally the number of results in
each bracket. The formula in each of those cells is:
where $E$20:$E$2519 is the range of output data, and the reference to G31
changes appropriately for each row of the histogram data table. The "% Scores"
column uses the following formula in each cell:
adjusting the I30 reference appropriately, of course, for each instance.
Below the table we created the bar chart histogram using the table as our
We constructed this model with 2500 iterations. Running the model
repeatedly (by pressing F9), we observe a great deal of variability in results,
so it would take a great many more iterations to have consistency. That
makes the problem an ideal candidate for the VBA approach, which we will
