Understanding Bell Curves at Age 11 - Math from D&D
I'd planned on writing some more about Call of Cthulhu this evening but a combination of family and homework have occupied my evening and necessitate a bit of a brief post tonight. And it's homework that got me thinking about statistics and RPGs. Currently I'm taking a Statistics class as part of my Strategic Analytics Master's program at Brandeis University. I'm diving deep into data science. My current statistics course is less focused with performing various statistical operations (though that is part of it) but rather with how best to present them.
