There is a Windows version of SPSS, and the company promises to release a student edition for that product. I reviewed the business version, which offers capabilities traditionally needed for a business statistics course. There is a social science adaptation as well. I had no trouble working with a file that had over 30,000 elements. The graphic capabilities of SPSS has traditionally been weak, and that is the case also for Studentware.
All plots are character, rather than pixel.
Line plots for time series data are not connected, and cannot even be plotted on one page in the portrait mode if the data set is relatively moderate in size. Studentware has no statistical quality control capabilities. Studentware has an excellent time series module, offering a full complement of exponential smoothing models. Studentware can find the optimal smoothing constants, and gave the most accurate results to my sample data of all the software I tried. Curve fitting is also available, with eleven trend-regression models possible.
