ENGR 123 (2023) - Home Page
Welcome to the home pages for ENGR 123: Engineering Mathematics with Logic and Statistics.
Connecting with us
Announcements will be made via the nuku announcement system.
The Course Coordinator is Dr Steven Archer
. The lecturers are Prof Peter Smith
Petes office hours are open door, if the door is open, take a punt! Stevens office hours are Tue/Wed/Fri 11-12noon in CO363 or whenver the door is open. You can also book in a time with either of us.
For administrative queries on assignments, tutorials and marking contact the relevent lecturer and
the coordinator in the same email
Dr Howard Lukefahr
is in charge of the labs, their supervision, report marking, and the lab content for this course. Any queries about those should go to Howard in the first instance.
See the time table
for an indication of when things are happening.
Tutorials start in week one and run in two flavours. See the time table
Labs are also on Thursdays, also starting in week one. Again see the time table
and lab resources
pages for details.
The class rep will be elected in week one of classes.
The Discord server link will be posted here.
Many staff are contactable by email details on this page
Content and material
Test one is on in week four, on Wed 6/12 in the lecture slot (12-2pm in HMLT001). Cover pages and formula sheets will be posted closer to the time.
Check the nuku announcements, email Steven and Pete if you still have any queries.
Both tests are out of 50, cover and formula sheets to appear here soon.

- Solutions to induction questions from the 2017, 2018 and 2019 exams.
Below are old discrete tests.
Here are sample test questions on statistics that are useful revision. Assignment 1 and 2 and tutorial 1 and 2 are also excellent revision. The test will cover all the statistics material up to the end of discrete random variables. There will be one question on data types, graphics and summary statistics, one question on general discrete random variables, one question on particular discrete random variables (binomial, Poisson, geometric) and one question on expectations. There will be no questions on continuous random variables.
Here are sample test questions (with solutions) on statistics that are useful revision. Assignment 3 and 4 and tutorial 3 and 4 are also excellent revision. The test will cover all the statistics material from continuous random variables onwards. There will be 3 questions, one on general continuous random variables, one on particular continuous random variables and one on estimation and confidence intervals.
Here is the statistics formula sheet
for tests one and two.
Here is the format of the statistics test
for test 2 as discussed in the lecture on 10 December. This gives you examples of typical questions which might be asked in the three questions. The first example question has a typo in the PDF - it should be multiplied by 2 so that the PDF integrates to 1.
Here is the cover sheet for discrete test two
The old discrete tests linked for test one are also good for test two.
There is no textbook for Engr 123.
Detailed lecture notes will also be posted on the course homepages from week to week.
See the course outline for an overview.
A quick summary is that Assignments are worth 25%, Labs 25%, Test one 25% and Test two 25%.
Videos Of Lectures
We record all lectures to video. To see videos of lectures, please follow the nuku link in the menu to the left.
The Mathematics Help Desk is a good place to come and ask questions if you are having trouble understanding tutorial and/or assignment questions, or material covered in lectures or in your extended reading. You are welcome here any time.
There is more help available from Vic's Student Learning. They will help you with ENGR123, and they can also help advise on study habits and how to pass courses. Take a look at their website:
This summer, student learning will offer study and writing skills workshops in November and will be available to support students in T3.
You may not be able to solve these problems initially, but we'll build up skills to make them accessible.
