To put the number into scientific notation: 2. Change the number 8.53 x 10-4 back to a decimal: a. On the Casio, press MODE key and then the number 9 again b. On the TI press the 2nd key and then the number 4 On either calculator the number will not show in decimal form. Allows you to find the log of a number using any base you want. Command Syntax. LogBASE(value,base) Menu Location. Press: ALPHA, then F2 (which is located over the WINDOW button) 5 or arrow keys to move down to logBASE(.
.If necessary, enter the name of the frequency list.With your cursor in the Store RegEQ line, enter the name of the function (Y 1, Y 9, or Y 0) in which the regression model is to be stored.To enter a function name, press a$ to access the shortcut Y-VAR menu and then enter the number of the function you want, as shown in the second screen.Press ENTER on CALCULATE to view the equation of the regression model.This is illustrated in the third screen. The equation of the regression model is automatically stored in the Y= editor under the name you entered in Step 5. Graphing a regression modelOften, it is a good idea to take a look at the scatter plot of your data to determine what type of regression model is best.

Here are the steps to graph a scatter plot of your data and the regression model on the same graph:.If you haven’t already done so, graph your two-variable data in a scatter plot or an xy-line plot.Set up the scatter plot by pressing 2ndY=ENTER. See Stat Plot1 in the first screen.Press ZOOM9 to see the graph of your data and regression model.This process is illustrated in the second screen.
