What you will study
This module builds on the statistics introduced at level 1 through the OU module Introducing statistics (M140). The module will investigate a greater range of statistical techniques than those introduced at level 1, and will also provide a deeper understanding of the techniques that were introduced.
In this module you will explore the fundamental statistical techniques which can be used to analyse data to answer real, practical, questions such as ‘Does drug A work better than drug B?’ and ‘How often do major earthquakes occur?’
The starting point for answering such questions is to model the variation in data: some of the most commonly used models for variation are considered in the first part of the module and some of their properties are investigated. The module then goes on to develop statistical techniques for using data and models of the variation to draw conclusions and answer questions of interest: the specific statistical techniques studied in the module include estimation, confidence intervals, hypothesis tests and regression.
An important skill for any statistician is the ability to communicate their statistical analysis clearly to others, both statisticians and non-statisticians. Statistical report writing is considered in one of the final units of the module.
In addition to the module texts, student learning is supported throughout by short video presentations, computer animations and online interactive practice quizzes.
You can find the full content list on the Open mathematics and statistics website.
You will learn
Successful study of this module should improve your skills in analysing and interpreting data.
Vocational relevance
The ability to analyse and interpret data is central to many careers in, for example, government, health, business, finance and market research. The material in this module explores the fundamental statistical techniques required for analysing and interpreting data. Statistical software packages are important data analysis tools for practising statisticians: the use of one such statistical software package is integral to this module. Another important skill required by practising statisticians, is the ability to communicate the results from their data analyses: this skill is developed through statistical report writing.
Entry
There is no formal pre-requisite study, but you must have the required mathematical and statistical skills.
You can check you’re ready for M248 and see the topics it covers here.
Talk to an advisor if you’re not sure you’re ready.
Preparatory work
You should aim to be confident and fluent with the concepts covered in the Are you ready? quiz here, and follow the advice in the quiz.
The key topics to revise include:
- algebraic manipulation
- logarithmic and exponential functions
- differentiation and integration.
Essential mathematics 1 (MST124) is ideal preparation, and Introducing statistics (M140) is also useful.
Study materials
What's included
You’ll have access to a module website, which includes:
- a week-by-week study planner
- course-specific module materials
- audio and video content
- assessment details, instructions and guidance
- online tutorial access
- access to student and tutor group forums.
You’ll be provided with printed module books, each covering one block of study, with many worked examples and exercises. You’ll also receive a printed module handbook.
You will need
A scientific calculator, but not one that is designed or adapted to offer any of the following facilities: Algebraic manipulation, differentiation or integration, language translation or can communicate with other devices or the internet. It also cannot have retrievable information stored in it such as databanks, dictionaries, mathematical formulae or text.
Teaching and assessment
Support from your tutor
You’ll get help and support from an assigned tutor throughout your module.
They’ll help by:
- marking your assignments and offering detailed feedback to help you improve
- providing individual guidance, whether that’s for general study skills or specific module content
- guiding you to additional learning resources
- facilitating online discussions between your fellow students in the dedicated module and tutor group forums.
Online tutorials run throughout the module. Where possible, we’ll make recordings available. While they’re not compulsory, we strongly encourage you to participate.
Assessment
The assessment details for this module can be found in the facts box.
Although your scores on the TMAs will not contribute directly to your final grade, you will need to complete most of them. However, the total workload for all TMAs is less than four standard TMAs. You will be given more information when you begin the module.
We’re using a new examination verification process for this module. We may ask you to attend a 15-minute post-exam video discussion, where you’ll present a photo ID and discuss your answers to a small number of questions with a tutor or member of the module team. The discussion isn’t graded; it’s only to verify that you completed the exam yourself.
