Table of Contents Use the hands-on exercises in this book to familiarize yourself with the basic features of the TI InterActive! [. . . ] Type the first airspeed, 30, and then press the down arrow key on the computer keyboard to move to the next cell. Type the next airspeed, press the down arrow key, and continue until you have entered all the airspeeds into L1. Type the sink rates in the second column in a similar manner, with the number in each cell corresponding to the number in the first column as shown in the table above. 34 Getting Started with TI InterActive! 6. With the cursor positioned at the end of the list, press Enter to create a new line. A group of buttons is click the down arrow displayed, representing the available graph types. In the uppermost text box, type L1 to specify it as the list containing the x coordinates. Press the Tab key to move to the second text box, and type L2 to specify it as the list containing the y coordinates. 7. If it is not already checked, click the check box at the left to select this plot. The points are not visible because they are outside the default viewing boundaries of the Graph window. Getting Started with TI InterActive! 35 Viewing the plotted data 1. The viewing boundaries are adjusted automatically to show all the plotted data. Click the Save To Document button to close the Graph window and insert the graph in the document. Calculating a regression on the data TI InterActive!lets you calculate several types of regressions on data stored in lists. In this exercise, you calculate a quartic regression on the plotted pairs of airspeeds (L1) and sink rates (L2). Position the cursor between the list and the graph and press Enter on the computer keyboard. Click the down arrow next to Calculation Type, scroll down through the list, and click Quartic Regression. After calculating a regression equation, you can graph it by entering this name in the graph. 36 Getting Started with TI InterActive! 4. In the text box labeled Y List, type L2. TIP: Before saving results to the document, click the check boxes next to the results you want displayed. 6. Click Calculate to calculate the regression equation and its variables. stores the results in variables, closes the Statistics Calculation tool, and displays the selected results in your document. Graphing the regression equation 1. With the cursor positioned at the end of the regression results, press Enter on the computer keyboard to move the cursor to the next line. Type the heading Graphed regression equation:, and then press Enter again. In the uppermost text box of the f(x) tab, type regEQ(x) and then press Enter on the computer keyboard. in the Graph window to adjust Getting Started with TI InterActive! 37 6.
