In addition, failure to take the test at the scheduled week results in loss of 10% points reduction for each week for that test.

• Quizzes: There are 10 quizzes or assignments, 10 points each.

• Attendance: There will be awarded 2 points for each full class attendance.

• TI83/84-Graphing Calculator is required for this course.

Introduction to exploring TI83 for Statistics

By Nellie Hedrick

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

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

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.

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

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.

MENU keys, some keys are considered as menu keys “VARS” key

VARS Key – Y-VARS is used with linear regression

MENU keys, some keys are considered as menu keys “Math” key and Matrix

Math Key –

Matrix - It may be in different location on your calculator

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.
