University of Sheffield, MAS113 Introduction to Probability and Statistics

Welcome to the web pages for the probability section of MAS113 Introduction to Probability and Statistics. This covers the first semester and about the first three weeks of the second semester. Course notes (excluding some of the worked examples from the lectures), exercises and solutions will appear here, in PDF format.

Information about the statistics section, lectured by Prof Jeremy Oakley, is available on MOLE.

Information about the course

For now, timetable information is provisional. In semester 1, lectures are on Mondays at 9am in Alfred Denny Building Lecture Theatre 2 and Tuesdays at 12 noon in Dainton Lecture Theatre 1.

There will be one other session in each week. In weeks 1 and 2 it will be a computer class, giving an introduction to the software package R, and in weeks 3 to 12 (excluding week 7, which is a reading week) it will be a tutorial. These sessions will be on Wednesdays, at either 9am or 11am depending on which group you are in; you can find out which group you are in and the name of your group's tutors at the SoMaS tutorial groups page. This will also tell you where the classes are.

For the tutorials, I will announce which questions from the exercise booklet you should look at in advance of the class. You should have a look at the questions before the class so that you have a good idea what you want to ask about; this is a much better use of the time available than if you only look at them for the first time in the class.

If you cannot make the time of your allocated group for a good reason, please email me and I will see whether I can move you.

Homework will be set after tutorials every other week, to be handed the following week. The work should be handed in to folders which will be placed outside room I9. The plan is that the homework deadlines in semester 1 will be on the Mondays 16 October, 30 October, 13 November, 27 November and 11 December. The homework is for feedback purposes.

Assessment is by an exam at the end of the module and online tests. The online tests for the module will be available on MOLE. The online tests in semester 1 will have deadlines on Fridays 6 October (not for assessment) and then 20 October, 3 November, 1 December and 15 December.

To contact the lecturer, email My office is I9, on the fifth floor of the Hicks Building.

A discussion board for this module is available on MOLE.

In some lectures I will use the L3cture app to run (non-compulsory) polls and mini-quizzes.
