Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

·         Understanding of and ability to interpret and manipulate mathematical statements. 

·         Subject knowledge through the recall of key definitions, theorems and their proofs.

·         Analytical ability through the solution of unseen problems in the coursework, test and exam.

 

Thus, the summative assessment for this module consists of:

·         One two hour examination at the end of the Semester; worth 80% module mark.

·         One Coursework, worth 20% module mark.

 

Formative assessment and feedback

 

Students receive written feedback via marked coursework assignment over an 11 week period. In addition, verbal feedback is provided by lecturer at practicals. 

Module aims

  • Introduce basic concepts of statistical modelling
  • study model fitting and selection for simple linear regression, polynomial regression and multiple regression models
  • consider and analyse simple experimental design models
  • use linear models in prediction and problems that may arise
  • use of R to apply theory to practical data analysis, using data from various areas of business and economics, science and industry

Methods of Teaching / Learning

The learning and teaching strategy is designed to provide:

A detailed introduction to the theory behind linear models using least squares estimation

Experience (through data analysis and R practicals) of the methods used to interpret, understand and solve problems in analysis

 

The learning and teaching methods include:


  • lectures with additional notes on white board to supplement the module handbook and Q + A opportunities for students

  • practical sessions using R to analyse data using the techniques learnt with lecturer/tutor walking around to support learning.



 

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
