|Session Name:||Three Statistical Tests Every Game Developer Should Know|
|Company Name(s):||Insomniac Games|
|Track / Format:||Programming|
"How much does this optimization really speed up my game?" can be a difficult question to answer when you're measuring differences of microseconds in highly variable framerates. "When I changed the minimap, 15% fewer playtesters got lost" might have been a fluke - or not - depending on how many testers you tried. Fortunately, statistical techniques exist to turn noisy, real-world sources of data like these into confident answers.
This talk is a succint how-to on statistics for answering questions like "does this new camera control scheme make players happier?", "how many players do I need to test this design change on to prove whether it works better?" and "does the framerate really get faster when I do this thing or is it just a fluke of measurement?" We skip past the mathematical background and cut directly to the practical how-to you can use in Excel today.
