Today, more than ever, statistics is part of our lives. From this key introductory module you will learn how to use basic statistical tools and quantitative methods that are useful in business, government, industry, medicine, the economy, and most academic subjects. Topics covered include: summarising data; examining relationships; randomness and sampling distributions; probability; testing hypotheses; and estimation. Using data from a range of applications, you’ll learn practical statistical techniques and fundamental principles, as well as using software and a calculator to analyse data. The skills introduced will be ideal if you plan to study more mathematics modules or if you encounter data in another subject or your daily life.
What you will study
This key introductory statistics module is designed for people who have not studied statistics before. It focuses on the application of statistics, adopting the attitude that statistics is about solving problems. The module is data driven. We collect relevant data and we analyse them to answer the problems. The methods that are covered are not specific to one field of application alone, but apply to all areas in which statistics is used.
The text contains many exercises that you should work through to help you learn and to monitor your own progress. Most exercises involve calculations that you will do by hand (or by calculator), but some you will do by computer, using the software package Minitab, which you will be taught to use and which is supplied with the module. You will be encouraged to develop skills in interpreting and communicating your results and this will be assessed in assignment questions.
Providing you have the appropriate background knowledge (see Entry Requirements) you should expect to study for about nine hours a week. Many of the topics covered in the module depend on your understanding of topics in earlier units. So, if you have not adequately understood earlier material, you may find later material difficult and time consuming.

You will learn
Successful study of this module should begin to develop your statistical skills and enable you to analyse common forms of data so as to address practical problems.
You will learn about:
- key ideas in statistics
- statistical vocabulary and notation introduced in the module
- selection and use of statistical techniques for exploring data
- interpretation of results in the context of real life questions
- communication of results
- use of statistical software
- use of relevant ICT tools for learning.
The module contains many data from real world situations based around three themes: economics, education and health.
This module may help you to gain membership of the Institute of Mathematics and its Applications (IMA). For further information, see the IMA website.
This module may also help you to apply for the professional award of Graduate Statistician conferred by The Royal Statistical Society (RSS).
You need no pre-requisites to study Introducing statistics. However, we recommend that you’re confident with the following mathematical topics:
- arithmetic of numbers, including negative numbers and fractions
- powers of numbers, including square roots
- using a scientific calculator for the above topics, and for working with brackets
- using simple formulas
- drawing and interpreting simple charts and graphs
Talk to an advisor if you’re not sure if you’re ready.
We provide free learning resources on our Maths Help website; you can learn new skills or refresh your existing knowledge. We recommend working through modules 1–6 and module 8.
Books, DVD, the software package Minitab 17, and a dedicated website containing online activities and resources.
You will need
A scientific calculator – we recommend any one that has basic statistical functions, such as mean and standard deviation, and that you know how to use it before the module starts. You will need a few household items to carry out a small experiment for one of the units of study.
A computing device with a browser and broadband internet access is required for this module. Any modern browser will be suitable for most computer activities. Functionality may be limited on mobile devices.
Any additional software will be provided, or is generally freely available. However, some activities may have more specific requirements. For this reason, you will need to be able to install and run additional software on a device that meets the requirements below.
A desktop or laptop computer with:
- Windows 7 or higher (a Mac is unsuitable – Minitab, the supplied statistical software package, will not run properly)
The screen of the device must have a resolution of at least 1024 pixels horizontally and 768 pixels vertically.
To join in the spoken conversation in our online rooms we recommend a headset (headphones or earphones with an integrated microphone).
