hello! I am a form 5 HK student . here, in the secondary school sci. calc. market, casios takes 98% of the market, sharps takes 1.5% and the 0.5% ard others. i have been using casios since 98 until last month, when i got a new hp20s. I am impressed by this calc, it is solidly bulit, has good keypad, many functions . its quite different from casios, I have practise for 2 weeks to become 70% familarized with it.
i would like to ask about the stat function:
suppose we have a set of data:
class mark: 5, 10, 15, 20, 25, 30
frequency: 8, 5, 8 , 10, 12, 9
in casios we can enter like this 5*8, 10*5, etc....
how about in hps? I cant find it and I have to use casios for stats in my exam. :-(
thanks in advance
