Abstract: 

We explore and discuss pedagogical opportunities presented by two subtle graphing calculator pitfalls that can be readily encountered in the secondary school classroom when doing statistics on common (TI) calculators: (1) confusion about bounds when computing cumulative probabilities for the normal distribution, and (2) confusion about the order of variables when computing regression lines of best fit to a dataset.
