Main Assessment In: April/May
Are reassessment opportunities available for all summative assessments? No
Reassessments are normally available for all courses, except those which contribute to the Honours classification. For non Honours courses, students are offered reassessment in all or any of the components of assessment if the satisfactory (threshold) grade for the overall course is not achieved at the first attempt. This is normally grade D3 for undergraduate students and grade C3 for postgraduate students. Exceptionally it may not be possible to offer reassessment of some coursework items, in which case the mark achieved at the first attempt will be counted towards the final course grade. Any such exceptions for this course are described below.
The course aims to
• enable students to apply correlation coefficients and simple linear regression models to quantify relationships in data;
• enable students to use bivariate probability models to assess the dependence between two random variables;
• demonstrate the importance and usefulness of statistical methods in real life via 3 case studies;
•promote an interest in probability and statistics and hence encourage students to study the subject further.
Intended Learning Outcomes of Course
By the end of this course, students will be able to:
• describe the difference between paired and independent data, and be able to recognise both in practice;
• calculate and interpret the sample correlation coefficient between 2 variables;
• fit a straight line using linear regression;
• construct interval estimates and carry out hypothesis tests in the context of correlation and linear regression, and interpret their results correctly and in non-technical language;
• carry out hypothesis tests for categorical data, and interpret their results;
• recognise the importance of checking assumptions wherever possible;
• explain how Statistics is used in different application areas;
• outline statistical modelling strategies used in different application domains;
• interpret the output of simple statistical models illustrating these modelling strategies;
• explain for some of these models how the calculations are performed;
•perform these calculations for simple examples.
