    hi , you probably want to copy - paste this into the maths section of this forum other than general chat, this is where the great helping mathematicians are to help . Also about cumulative frequency, first you need to make a table with frequency and X (whatever you are studying , eg. weight , height or whatever), then have a row underneath with cumulative frequency, this is adding the frequency up as you go along. You can then plot this on a graph with frequency on the y axis and x on the x axis

    why have people been topping old threads today? besides, as someone said, you're a bit late. they probably took their exam and failed, all because you were too late.
