The versatiliy of the actual calculated question type has the consequence of a three pages editing process with a lot of variables to set.
I propose to add a new questiontype i.e simple_calculated that will be a limited version of the actual calculated using most of the actual calculated question code but with fixed options that will simplify the edtion to a single page.
1.Only tolerance as used in numerical will be allowed for the asnwers.
2.Only private datasets will be allowed.
3.The dataset parameters will be minimum, maximum and number of significant figures.
4 The number of dataset items will be 10, 20, 50 or 100
5. A table will show their values and identify possible conflict with tolerance and significant figures
5.The dataitems could not be edited.
6. The question could be upgraded to a normal calculated question.
7. All the question processing will use the same database tables and most of the actual code of calculated question.
8.This code will be part of moodle core code as it does not add a significant charge to maintain it.
