Question in Stats
This questions assesses the ability to conduct an ANOVA and interpret the results.
Adaptive marking: an error in calculating F can be carried over to the calculation of the p-value as well as the test conclusion.

Question in Demos
Give the student three points lying on a quadratic, and ask them to find the roots.
Then ask them to find the equation of the quadratic, using their roots. Error in calculating the roots is carried forward.
Finally, ask them to find the midpoint of the roots (just for fun). Error is carried forward again.

Question in Christian's workspace
The student must perform an indefinite integration, and include a constant of integration.
A custom marking algorithm identifies the name of the student's constant of integration, and replaces it with 'c' before comparing with the expected answer.
If the student enters something like '2c' instead of 'c', it'll be marked wrong, which is an error in the marking.
