The tutor focuses on the Staples BD-6120G, which has some convenient features.<\/h1>\n

Overlooking the Staples BD-6120G might be easy: I can’t recall any of my students using it. Yet, I picked one up from Staples’ abundant shelves; someone must use it.<\/p>\n

As a scientific calculator, the BD-6120G is all my students would need; moreover, it has graphing capabilities. While perhaps not so powerful as the TI-83 family of graphers, the BD-6120G could probably get the user out of most high school jams.<\/p>\n

Today I’m looking at how to do linear regression with the Staples BD-6120G. Specifically, suppose you want to fit a model equation of the form y=a+bx to the following data:<\/p>\n\n\n\n\n\n
x<\/strong><\/td>\ny<\/strong><\/td>\n<\/tr>\n
4.1<\/td>\n2.3<\/td>\n<\/tr>\n
10.8<\/td>\n6.1<\/td>\n<\/tr>\n
21.4<\/td>\n15.2<\/td>\n<\/tr>\n<\/table>\n

With the Staples BD-6120G, here’s how:<\/p>\n

    \n
  1. Turn the calculator on. Press the mode<\/span> button, arrow over to reg<\/span>, then press =, at which time lin<\/span> will appear on the screen. Press = a second time to choose linear regression. Afterwards, reg<\/span> will appear in the top-left corner.\n<\/li>\n
  2. From the table, enter the data pair (4.1, 2.3) as follows:
    \n4.1 shift<\/span> hyp<\/span> 2.3 M+<\/span>
    (An unexpected graph might appear as you do this; just ignore it and continue:))\n<\/li>\n
  3. \nRepeat Step 2 for the next two data pairs in the table.\n<\/li>\n
  4. \nTo get the equation of the form y=a+bx, you need the values of the a and b parameters. To find a, press shift<\/span> 7 = (which yields, in this example, -1.279495773). To find b, press shift<\/span> 8 =<\/span> (which yields, in this example, 0.755881193).\n<\/li>\n
  5. \nIt’s best not to forget to actually write the equation with the values for a and b substituted in. For this example the regression equation is as follows:<\/p>\n

    y=-1.27950 + 0.75588x <\/p>\n<\/li>\n<\/ol>\n

    Best wishes with this technique!<\/p>\n
