Below is a Microsoft Excel file which contains a probabilistic forecasting game.  It was developed about 5 years ago by Mark Roulston at Pennsylvania State University.  The file is a bit old and has a few minor problems which I will describe.
 
All participants will go through this game next Monday if possible.
 
First, the file contains macros.  If it does not work or does not open properly, please change the macro security settings to medium by clicking on Tools then Options then Security then Macro Security then select medium.  Then you will need to close the file and open it again. 
 
(Tools>>Options>>Security>>Macro Security>> select medium then OK)
 
The two probems are
1.  When starting the game, you will have to enter some information.  Just click on any choice (it makes no difference) and click on OK or click the X on the top right of the dialog box .  I am not able to remove this step.
 
2.  If you do not complete the exercise, the file will not close.  You will have to use Task Manager to stop the program.  This was due to the fact that the game was once used for research and students were paid to do it.  They had to complete it.  I cannot remove this requirement.
 
Please test the attached file and tell me if you are able to play the game.  You can do all 90 days if you want but it is not necessary.  You can force the program to close once you try the first few examples.
 
Thanks.
