    Use the GDC, Press STAT, first menu is edit, press 1 on edit enter in the data
    turn on diagnostic: 2nd function, catalog, scroll to diagnostic on, enter, enter
    STAT, tests, you'll see a variety of functions pick the one with highest r and r squared values. Does that help?
    Feel free to REP me..
    btw where do you go to school?

    Hi. Sorry to bring up an old post (again) but I'm completely lost by the formula thing for this IA? One of the conditions was to like find the formula/graph thingo by NOT using technology? And my teacher mentioned something about a regression graph on the computer? Can anyone please shed some light on that thing? And do I just use the y=a+bx formula?? or do i actually have to use something with the e^(-x) thingo cause i have no idea how to do that... ><

    By "Define all Variables", it should mean simply stating the variables and factors that can affect the dropping of the nut. If you have done physics, chemistry, bio or whatever, reports, it will be similar to "Control of Variables".
    this man has done an excellent job with the explanation of define the variables but what are the parameters guys?

    the exact wording is "define all variables used and state any parameters clearly." so if we assume the variables are things like wind speed stays constant etc. etc. then what is the second part of that?
Do you agree with the PM's proposal to cut tuition fees for some courses?
