Dealing with Data

1. Dealing with Data Basic Steps to Using the TI-83 Graphing Calculator

2. What we are going to cover • Graphing functions • Data Lists • Graphing Lists • Regression Analysis • Programs

3. Guess What? Everything you will see today you could do with a spreadsheet or graphing program

4. 1. Lists • 6 columns that hold data • Data can be manually entered • Hit STAT then Edit (choice 1) • Use the arrow keys to navigate between lists • To clear a list: • Highlight the list name • Hit clear then enter

5. Some List Data From Me 2 You

6. 2. Graphing Lists • Hit 2nd then STAT PLOT • Turn on plot (others off) • Graph type • Data locations • Mark type

7. 3. Setting the window • Manually enter values • Automatically by using a ZOOM feature, such as Zoom, then 9

8. 4. Graph the data • Press Graph (for manually set windows) • or Zoom, then 9 (for automatically set windows)

9. 5. Determine line-of-best-fit (regression analysis): • Choose STAT • Use the arrow key to navigate to CALC • Select the type of statistical operation you wish to perform • The operation will be performed on the active plots.

10. Graphing Functions • You can specify an equation to graph • Y = button • Enter the right side of the equation • Use the X,T,θ,n, button to insert a variable • Hit GRAPH to see the plot

11. Programs • With programs on the TI-83 • You can automate processes • Share them from calculator to calculator • Connect to and use external devices such as sensors

12. Transferring Programs • Connect two calculators using the link cable • Hit 2nd then LINK • Use the left and right arrow keys to choose between send or receive.

13. Running Programs • Hit PRGM • Select the program you want to run and hit enter.

14. Homework • Learn how to do one new thing on your calculator. • Turn in a brief summary of what you learned and step by step directions for how to do it.
