Features of the TI-83

The restyled TI-83 offers graphing tools for mathematics and science coursework, including statistics and finance. The TI-83 is the predecessor to the upgradable TI-83 Plus.

Computer Connectivity with TI-GRAPH LINK™
TI-GRAPH LINK is your link to connecting your TI-83 to your computer. This software and cable (sold separately) allows for transferring your files and data between the calculator and computer.

TI InterActive!™
TI InterActive! is a user-friendly, integrated computer software environment that combines the functionality and familiarity of the TI-83 Plus graphing calculator with the desktop publishing capability of the computer.

Key functionality for math and science.

Graphical analysis
See the equation, graph, and coordinates all at the same time. Jump directly to points just by entering a number.

Plots
Four plot types including scatter, box-and-whisker, xy-line, histogram, and normal probability plots.

Data Analysis
Choose from eight regression models and four plot types. Available regressions include median-median line and quadratic, cubic and quartic polynomial regressions.

Advanced Statistics and Regression Analysis
Includes hypothesis testing and confidence intervals. View results graphically or numerically. Analysis features sine and logistic regressions.

Graph-table split screen
Allows you to trace the graph and scroll table values simultaneously.

Matrices
Store and analyze up to 10 matrices, size limited only by available memory.

Equation Solver
Solve equations interactively for different variables. Great for "what ifs."

Data lists
Store data in lists containing up to 999 elements per list. Great for storing and manipulating real-world data collected with the CBL™/CBL 2™ or CBR™ System.

Tables
View and evaluate function variables in numeric table format.

Functions
Define, save, and graph up to 10 rectangular, 6 parametric, and 6 polar functions, in addition to 2 recursively-defined sequences.

Programming
Includes keystroke programming commands for conditional tests, jumping, and loops. Assembly language programming capabilities.

Data Collection
This tool is compatible with the CBL 2™, CBL™, and CBR™ for collection and analysis of real-world data.
