Question in Bin
A measurement is performed multiple times for the same object, the student will
- calculate the mean result
- calculate the standard error on the mean
- write the mean±error to the correct precision as defined by the error written to 1 significant figure
Advice is provided including on performing the calculations in Python or spreedsheets together with further reading.

Question in MESH
The student is presented with a scenario then asked to select a sample size to investigate and the number of bins for a histogram of the data. Theoretical distributions of normal, uniform and lognormal distributions can be overlayed on the histogram. Student is asked to identify the most likely distribution and the mean of this distribution (within a +/-10% margin of error).

Question in Content created by Newcastle University
A question testing the application of the Cosine Rule when given two sides and an angle. In this question, the triangle is always obtuse and both of the given side lengths are adjacent to the given angle (which is the obtuse angle).
-
Question in Engineering Statics
Solve for an angle which will result in equilibrium for a triangle subjected to three couples. A trial and error solution is recommended.
-
Question in Stats

Printing errors in the work produced by a particular film occur randomly at an average rate of p per page.
i.What is the probability that a one page document will contain x1 printing error(s)?
ii.If a n page document is printed, calculate the probability of having more than x2 errors. Assume a Poisson distribution. -

Question in Linear Algebra 1st year
In this demo question, you can see either 2 or 3 gaps depending on the variable \(m\), and the marking algorithm doesn't penalise for the empty third gap in cases when it is not shown.
Reason to use it: for vectors or matrices containing only numbers, one can easily use matrix entry to account for a random size of an answer. But this does not work for mathematical expressions. There we have to give each entry of the vector as a separate gap, which then becomes a problem when the size varies. This solves that problem. For this reason I've included two parts: one very simple one that just shows the phenomenon of variable number of gaps, and one which is more like why I needed it.
Note that to resolve the fact that when \(m=2\), the point for the third gap cannot be earned, I have made it so that the student only gets 0 or all points, when all shown gaps are correctly filled in.
Note the use of Ax[m-1] in the third gap "correct answer" of part b): if you use Ax[2], then it will throw an error when m=2, as then Ax won't have the correct size. So even though the marking algorithm will ignore it, the question would still not work.
Bonus demo if you look in the variables: A way to automatically generate the correct latex code for \(\var{latexAx}\), since it's a variable size. I would usually need that in the "Advice", i.e. solutions, rather than the question text.
