Craps players might get this sooner, but it is just a simple record of "Decisions" on a Craps table.
Each horiztontal row tracks a series of rolls; the series ends with either a "7-out" or the "point" being made.
So far, so easy...

What I'm having trouble with is the following:
As you might know (or guess) the normal distribution is a bell curve like result with (out of 36 roles) 7s being the most frequent (6 events), followed by 6 and 8 (5 each, etc...)
e.g.- see Probability Distribution Table on sheet.

Anyway, I'm trying to find some way to graphically represent 2 things:
1- The normal Bell Curve like distribution of an ideal "X" # of rolls. ("X" = whatever the roll total is to that point. Represented as a perfect distribution.)
2- The actual count of "incidences" of each number thrown.
(Represented, preferably, as vertical bars.)

Thus ennabling me to quickly see discrepancies from normal distribution...

Is this possible?
I hope so!

Thanks,
Ken
 

Excel Facts

Links? Where??
If Excel says you have links but you can't find them, go to Formulas, Name Manager. Look for old links to dead workbooks & delete.

Got it!

All I needed was COUNTA/COUNTIF formulas and a chart of the results.

Nothing like a good nights sleep. :)

Thanks to all who viewed it.
