Rossman, Beth L Chance and J. Barr Von Oehsen • TI83/TI83 plus website:http://www.occc.edu/statistics • Office/Hours: Math Adjunct Office, Saturdays: 7:30am – 8:00am , 5:00pm – 6:30pm

  3. Grading • Grades are based on the accumulation of points. • Points are based on: • Completion of assignments or quizes • 3 Major exams, 100 points each • Grades are posted in Angel online and updated Sunday after the deadline. • Our Grading Scale • 90-100% = A • 80-89% = B • 70-79% = C • 60-69% = D • Below 60% = F • Grades are calculated on cumulative percentage

  10. Introduction to exploring TI83 for Statistics By Nellie Hedrick

  11. Calculator Introduction • Different design Calculators are now available for TI83’s. • Regardless of the design, you should be able to find about 5 different color buttons. • In the picture; • Off white keys: Number Keys • Blue keys: • Function keys on the top • Direction key- top left • Operation keys (+, -,* and /) • Yellow key - 2nd Key  • You have to press this key first before using the yellow text of the face of the calculator • Green key - Alpha Key  • You have to press this key first before using the green text of the face of the calculator • Black keys

  12. Some of the important keys you need to knowYou need to install TI83 plus fonts to see the key strokes • Different between “(-)”  and “–”  keys • Minus –  Key is used for subtraction • (-)  key is used for indicating the sign of the number • See the difference in the picture •  Enter key – used as “=“ or process an operation • Open and closed parenthesis “(“and “)”  • Comma Key  • Math key * • to quit any menu or operation press [QUIT] by pressing  keys • Clear key  • Stat key  * • VARS Key – * • DISTR  Key press  * • Stat Plot press 2nd Y=   • Window  • Zoom  • Graph  • Matrix  - 2nd x-1   • 2nd x2  will give you square root * Menu Keys

  13. MENU keys, some keys are considered as menu keys “STAT” key  STAT Key – When you press the STAT key , you will get multi menu and options to go from one section to another press right arrow key from your calculator. Use the down arrow key  to see all the option within each section.

  14. MENU keys, some keys are considered as menu keys “DISTR” key  DISTR Key – When you press the , you will get multi menu and options to go from one option to another press right arrow key from your calculator. Use the down arrow key  to see all the option within each section

  15. MENU keys, some keys are considered as menu keys  key Stat Plot Key – . Press key to view the plotting option 1. You can turn ON and OFF all the Stat-graph you have done with is menu. WHEN finished turn all the plots to OFF status. (option 4 from Stat plots menu.

  16. MENU keys, some keys are considered as menu keys “VARS” key  VARS Key –  Y-VARS is used with linear regression

  17. MENU keys, some keys are considered as menu keys “Math” key and Matrix Matrix -  It may be in different location on your calculator Math Key – 

  18. This was a quick reference to some of the keys we will be using in this class. Their detailed-use will be covered as we cover the course.
