TI's approach is to get involved by going into classrooms to find out what teachers need. They work hand in hand with leading educators, listening to the needs of the mathematics community. Univariate analysis might include asking a classroom of seventh graders to line up by height in front of a black board, marking off their height on the board, and then performing basic analysis, finding median and quartiles. For more advanced students, it might mean researching medians of standardized test scores for students in different states or the batting averages of National League baseball players. The TI-82 makes scatter plots that result from such investigations.
Students can then look for relationships in the arrangements of points.
They can then make predictions based on their data analysis. The TI-82 Graphics Calculator will begin shipping worldwide to dealers, educators and retail outlets in June. It will be covered by a one-year limited warranty against defects in materials and workmanship. All rights reserved.
