This is a general question about the AP Stats curriculum even though I do refer to Workshop Stats by Rossman:
I noticed in Workshop Stats that the data files on disk have every data item entered separately even when the data is given as tallies in the book (for example in Activity 3-10 (d,e)). It is clear from previous emails that dealing with frequency data is difficult with Minitab. However, it is very easy to do on the TI-83 (stat calcs and plots all will handle frequencies). Ignoring the importance of thinking about this topic as it applies to general statistics (it is important) do our students need to be able to handle data in this way for the AP Exam? I assume they do but am I right that they will not have to use the calculator to actually calculate data with frequencies?
