    I was wondering how often you're required to input a frequency table into a calculator in order to calculate the variance/standard deviation. (i dont know how to use my calculator - i wrote it down on paper but my teacher collected it in and never gave it back and now im screwed - its a texet albert 5; if anyone can help with that too)

    thanks )
