# Introduction to Statistics

## Module description

Summary:
This module aims to provide knowledge of how to summarise and analyse data, to provide an insight into the concepts of probability and stochastic independence, understanding of statistical methodologies for testing hypotheses, and to provide skills in using statistical software.

Please note that this module cannot be taken with Statistics for Business and Management (BEE1025) or Introduction to Statistics for Accountants (BEA1012) or Statistics for Business (BEM1024).

This module requires students to have at least a Grade B in A-Level Mathematics (or equivalent). This module is not available to maths students.

Internationalisation

The content of this module is universal and applicable around the world. It includes international examples with real statistical data from countries such as China, India, Europe and the UK.

Employability

Knowledge of statistics is essential for any business or economics student, so this module provides students with a valuable theoretical and practical understanding of the subject, as well as weekly assignments that enable them to work consistently with continuity and discipline.

Sustainability

All of the lecture notes and tutorial sets are available on the ELE (Exeter Learning Environment).

## Module aims

The module aims to provide students with an understanding of the role of statistical methodologies in economics through both the study of the theory of probability and statistics, and hands-on practice using Excel with a variety of data types.

## ILO: Module-specific skills

• 1. construct charts and calculate appropriate descriptive statistics to summarise a data set;
• 2. understand discrete and continuous random variable, their distributions and moments;
• 3. solve a range of problems involving probability;
• 4. understand covariance, correlation, conditional probabilities and conditional expectations;
• 5. conduct hypothesis tests and interpret their results;
• 6. demonstrate the ability to utilise a software package (Excel and Stata) for a range of statistical applications.

## ILO: Discipline-specific skills

• 7. demonstrate awareness of the role of numerical evidence in economics;
• 8. demonstrate understanding of the advantages, disadvantages, and limitations of different quantitative methods.

## ILO: Personal and key skills

• 9. demonstrate quantitative, computational and computer literacy skills.

## Details of re-assessment (where required by referral or deferral)

Original form of assessmentForm of re-assessmentILOs re-assessedTimescale for re-assessment
Homework quizzes: 5 each at 4% (20%) Any quizzes deferred will be set-aside*; any quizzes failed will also be set-aside* if the module is failed overall**August/September Reassessment Period

## Re-assessment notes

Deferrals will take place as soon as possible within the same term; Referrals** and any further deferrals will take place in the August/September Reassessment Period

*’Set-aside’ means that assessment is excluded from the overall module mark, and an overall mark is calculated from the remaining assessments with those remaining assessments re-weighted in proportion to produce a mark of up to 100%.

So for this module, if one of the quizzes (4% of the module) were to be ‘set-aside’ the marks for the remaining components would be added together and the maximum effective mark would be 96%. This would then be re-weighted to produce a mark up to 100%.

**If you pass the module overall you will not be referred in any component – even if you have not passed one or more individual components.
