what the fuck is an mean median mode

hi bitchez sorry for being inactive my school stopped letting me using the computer for a long time (bc i gave the computer a virus trying to watch girl interrupted on a piracy site) and that's my only access to the interwebs but they're letting me use it again!!

also does anybody know what a mean or a median or a mode is?? i need it for my math class bc i didn't pay attention to what ms. beech said about it
