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 Toby's workspace

Question in Maura's workspace
Tests students' ability to apply the recursive form of the Extended Euclidean Algorithm. Random fourdigit inputs are chosen subject to the condition that the Euclidean Algorithm terminates in seven steps.

Question in Maura's workspace
Asks students to add and multiply two integers modulo another integer. The modulus is a random number between 30 and 70, the summands are set to be large enough that modular reduction will be necessary.

Question in Maura's workspace
Asks students to compute the multiplicative inverse of $a$ in $\mathbb{Z}_n$ where $n$ is an odd number between 31 and 61 and $a$ is an integer coprime to $n$ that lies between $n/4$ and $3n/4$.

Question in Maura's workspace
This question tests students' ability to use repeated squaring to perform modular exponentiation. Moduli are random numbers between 30 and 70, the base is a number between 10 and 29. To generate questions of approximately uniform difficult the exponent is taken to be 256 plus two smaller powers of 2.

Question in Maura's workspace
A straightforward test of encrypting and decrypting an eightletter message with the Vigenère Cipher using a fourletter key. Message letters are generated uniformly at random from the English alphabet, as are the key letters. Students are expected to be able to map English letters onto elements of $\mathbb{Z}_{26}$ in the usual order.

Question in Maura's workspace
A straightforward test of encrypting and decrypting an eightbit message with the Vernam Cipher. The message and the key are uniform and independently generated eightbit strings.

Question in Maura's workspace
A straightforward test of encrypting and decrypting an eightletter message with the Substitution Cipher. Message letters are generated uniformly at random from the English alphabet and the key is a uniformly chosen random permutation of the alphabet. Students are expected to be able to map English letters onto elements of $\mathbb{Z}_{26}$ in the usual order.

Question in SIT281
The purpose of this question is to ask the students to go through one Rijndael round from the AES algorithm.

Question in Maura's workspace
A straightforward test of encrypting and decrypting an eightletter message with the Caesar Cipher. Message letters are generated uniformly at random from the English alphabet, as is the key. Students are expected to be able to map English letters onto elements of $\mathbb{Z}_{26}$ in the usual order.
