Cleanroom Combinatorial Example
A Cleanroom combinatorial table can be constructed for any of the player usage pro-
files you define. For this example, you will create one such table for the “Casual�? player.
To decide which value to choose for each parameter, you need a random number
source. You could think of a number in your head, write a program to generate a list
of numbers, or roll electronic dice on your PDA. Microsoft Excel can generate random
numbers for you with the RAND( ) function or the RANDBETWEEN( ) function if you install
the Analysis ToolPak add-in. There is no wrong way as long as the number selection
is not biased toward any range of numbers.
