Most of us struggled through an undergraduate statistics course and afterwards put it gratefully to one side in the firm expectation that we would never need to look at it again. After all, if you don't intend to be a professional scientist you aren't going to be doing experiments and analysing the results, surely?

It can come as a bit of a shock a few years later that you need to make some recommendations and back up your thinking to your colleagues and superiors. Or perhaps you are having to make decisions on the basis of reports and statistical analyses that are being submitted to you. It looks as though you do need that statistical knowledge after all, to analyse the information and present a good case. If only you could remember a bit more about it. Perhaps you had never really understood it – and if you don’t have a mathematical background, this is all too likely given the way that Statistics has historically been taught.
Most people hated learning Statistics, and most people remain uncomfortable with it throughout their working lives. However, it doesn’t have to be like this. Statistics for the Terrified is a valuable resource to help you refresh your knowledge.
Statistics for the Terrified evolved out of a series of ‘refresher courses’ in the early 1990s, for people in just this position. Typically they had all taken statistics as part of their training, but unfortunately, they had gained no real understanding of how it worked and felt that it would always remain something of a mystery. Like most people, they just wanted to know how to use statistics in their work: they were not at all interested in Statistics as a subject, or in complex mathematical proofs of how techniques worked. Their main concern was that their work should not be jeopardised by bad statistics.
As well as covering all the basics in straightforward english rather than mathematical language, Statistics for the Terrified includes a set of rules of thumb which will enable you to select most appropriate test for your data.
Although the tutorial does cover some quite advanced topics, it approaches everything in a basic, common sense way. Having gained an understanding at this level, you will be able to approach reference books (and talk to statisticians!) much more confidently.
You can go back to the very beginning, with probability, means and medians, etc.: or you can pick up your statistical studies again at any point which suits you. The material is broken down into “The Basics” (which introduces the fundamental principles), and “Testing and techniques”, which will take you through the different ways these principles are applied.
We introduce four basic layouts of data which correspond to the most commonly-used tests, and which show you how and why they are appropriate. After completing this section (“How to choose a test”) further sections give more in-depth explanations of the various tests and techniques. You can cherry-pick the bits you need right now, or work through it in detail: the control is always with you.
These later sections include a series of challenges and puzzles which you solve by changing the data. The data points on our dynamic graphs are your game pieces, which may be moved in any direction. You are guided through a number of scenarios, encouraged to experiment and observe changes in the resulting statistics, finally being challenged to generate particular outcomes. Although you may not understand the statistical processes at first, by the end you will have a clear intuitive grasp. By presenting the data simply and graphically, the software makes the results of your actions clear and easily understood.
You will develop confidence in your ability to collect and analyse data in the most appropriate way, and also to understand what a statistical analysis is really telling you. You will be able to see if someone’s data really does support their project, or if they are lost in wishful thinking; and you will be able to avoid making such mistakes yourself.
And someone who understands statistics will always be valued in the workplace.
"Our students who have made full use of Statistics for the Terrified have universally found this to be an extremely useful resource in getting up to speed... Keep up the good work!"

"Well, I aced my stats course and I have to give credit to your program. It gave me straight forward explanations about some terrifying questions and I could go back and review as many times as I needed. All in all, you have a great product."

"I have found Statistics for the Terrified to be a valuable tool in helping students to grasp some core concepts in statistical testing such as the standard error, confidence intervals and hypothesis testing. I have found the interactive multi-media element of Statistics for the Terrified to be particularly powerful in this regard."

"Congratulations for this fantastic piece of software. Certainly your software does fulfill my needs, and it also proves useful when it comes to just refresh a specific topic. One could consider it as well as an “ongoing refresher course”, very handy not only for beginners in statistics. Let me know if and when new versions are out. And BTW, it works perfectly under Windows 7 Ultimate."

"Concept Stew supported us from start to finish in implementing this for our students – from providing the software in the most appropriate format for our needs to offering a support line for our students, they have been with us all the way, and always with a cheery message to make us feel like valued customers. We’re looking forward to working with them as the product develops."
