    When using LinReg, after you enter the two lists, add another comma followed by Y1, and the equation will be placed into Y=. To add Y1, go to Vars > Y Vars > Function, and then choose Y1.

    I watched many videos about scatter plotting. On all of them I got lost after Zoom 9. Your video finally made it clear to me. I know have it written down as 9 steps on the note card that I will be allowed to use for my exam. Thank you so much!

    I'm on yt because my text is a bit weak explaining correlations and I didn't know how to do them in my TI-84. This was so helpful. Not just the steps, but also the explanation that the coefficient of variation is the percent of variability in the y value that can be accounted for in the x variable. It seems like the unifying concept, but my book didn't touch on it.

    You did great I am trying to past stats online, no one has shown me how to do this TI-84 calculator, thank you for helping me. at least if I know how to use and place the linear correct, I can learn stats. Thank you

    I can't seem to get the r and r square on my calculator. It only shows the a and b and the slope intersect form. Anyone help?

    • @ProfTaormina
      @ProfTaormina  4 года назад

      You'll need to turn the Diagnostic On. Use the catalog function on your calculator and scroll down to Diagnostic On and click Enter.

  • @psnGoBoSox
    @psnGoBoSox 11 лет назад

    we learned this in class, but i have a problem that you may be able to help me with. i have entered all data up until this point. when i am in the "y=" and go to y-vars>funtion, only "y1, y2, etc." appear rather than the actual equation for y1, y2, etc. as it did in the example our professor gave us.
    the problem is when i would enter just "y..." in my y= menu, then try to do anything, it would tell me the error lies in the lack of a equation after "y=Y1"
    is there any way to remedy this?

    1 question: If we wanted to write down the equation of the line with fractions, how would we change it?

    • @ProfTaormina
      @ProfTaormina  10 лет назад

      You can turn terminating decimals into fractions on the calculator by first entering the number, then press the MATH button, then press 1:Frac. Using the fractions, you can rewrite your regression equation so the coefficients are in fractional forrm.

    Im getting some different values on my Ti-84 Plus. I got 15 for a, 202 for b and r value= .725. Any thoughts on why this is happening?

    • @ProfTaormina
      @ProfTaormina  10 лет назад

      I would suggest double-checking that the numbers in your two lists have the correct values.

    **I meant don't manually type the EQUATION into 'Y1'.**
    On the new TI-84 operating system, it gives you a menu where you fill in the blanks with L1, L2 (default), and you need to type Y1 using the VARS > Y-VARS > Function... > 1: Y1 menus in order to automatically get the equation put into Y1 for you.

  • @andrewxc1335
    @andrewxc1335 11 лет назад

    @9:00 - DO NOT manually type in the data, unless your teacher is perfectly happy for a rounded version. If you want the exact values to be plugged in automatically, so that you get exact answers, type in the 'LinReg(...)' command, then 'L1,L2,' At the end, you want a third argument: where to store the function.
    Go to (next to 'Clear') VARS > Y-VARS > Function... > 1: Y1.
    Hit Enter after the three arguments, and you will not need to plug in the equation manually.
