We’re using several data sets to practice linear regressions with the graphing calculators. Let me share a few. This guide has fairly clear instructions with steps to follow. These same instructions work with either the TI83 or TI84 graphing calculators.
1. Here are 17 data sets for practice with an answer key.
2. This Regressions Packet has Quadratic and Exponential regressions, along with Linear regressions. Teens can try different equations in STAT to see which equation best fits the data. This is a form of math modeling.
3. This worksheet has graphs to graph by hand or to sketch the graph from the graphing calculator. N.B. None of the data in these problem sets is at all interesting.
