Statistics

[hgeorgsch]

For the purpose of evaluation, both of the model and of the question list, it is necessary to get statistics from the module. It should be detailled but anonymised.

The first step is to document and exemplify the possibilities that already exist. These should be reviewed before new features are added.

Reports of interest include.

1. Question usage and rating over time.
2. Student ratings and activity over time.
3. How many times do each student answer each question correctly and falsely.

The time element is important here. We need to understand the dynamics of the ratings.
What is possible to do?

The CSV/openoffice exports are good as raw data. I shall have a look at them and see what kind of visualisations and aggregate statistics could be useful. I keep this issue open to elaborate on desired report formats.

There are a couple of improvements to be made to the raw data dump, too, but these are reported as separate issues.
