Shift-Click the Flag. Make sure it says "Turbo Mode". Click the Flag. When you see "Number of Discs", type a small whole number in (try 12), and then click the blue check-box. When you see "Number of Games", type a large whole number in (try 50000), and then click the blue check-box. Wait until you see several black squares on the screen. At this point, you may: Press S to show variables. Press H to hide variables. Press L to hide or show graph ranges. Press R to reset variables and delete lists. Click the Flag to start over.
The purpose of this program is to find the average number of creepers-killed-by-skeletons it takes to collect at least one of each of all the music discs in the video game Minecraft. I used a very tiny bit of knowledge of statistics to make this. I drew inspiration from the game Minecraft. In the Bukkit ASkyBlock Plugin, there is a "challenge" in which one must collect all of the available Minecraft music discs. There are 12 types of music discs, each with an equal probability of dropping from a creeper killed by a skeleton. What I wanted to do was to find the average number of creepers-killed-by-skeletons it takes to collect at least one of all the music discs. In the program, I used purple blocks to organize my code into separate functions. There are two purple blocks, which find mins/maxes of lists and graph them, which I incorporated from my backpack of scripts. When you type in "12" for number of music discs and "100000" for number of games, you will get an interesting pattern of black squares at the end. In statistics, that shape is known as a skewed distribution (I don't know exactly what the name of the distribution is, or what it theoretically should be.). It is asymmetric, unlike the "normal" distribution bell-curve.
