There is a typo in the quota sample instructions. While SAMP's appearance has caught up with the fashions of the times, its mental abilities have not. To be blunt, it doesn't do a heck of a lot, considering the price and complexity. It is far from flexible. In stratified sampling each stratum must have the same N, which makes it impossible to show how one can improve precision by shifting cases from solid to iffy subgroups.
Users can store only one sampling for each method.
More telling, SAMP has not become more ambitious, just more attractive. Let me cite three areas. First, it prints cost-effectiveness numbers such as call backs, travel time, and interviewer pay. But these are just boiler plate print statements. I am shocked, shocked I say, that a Management School would not build in routines to simulate the likely cost of various sampling schemes.
