This free course provided an introduction to studying Mathematics and Statistics. It took you through a series of exercises designed to develop your approach to study and learning at a distance, and helped to improve your confidence as an independent learner.

First, you need to decide what it is you want your chart to illustrate. This may be governed by the data you have access to or you might need to collect the data yourself. Then the process is as below.

1. Decide on a clear title.

The title should be a brief description of the data that you want to show.

2. Identify how many bars are needed.

The bars correspond to the number of categories you have. For instance, if you are look

After studying this course, you should be able to:

• reflect on the reasons for needing to improve skills in using charts, graphs and tables

• understand the following mathematical concepts and how to use them, through instruction, worked examples and practice activities: reflecting on mathematics; tables; line graphs; bar charts and histograms; pie charts; analysis

• draw on a technical glossary, plus a a list of references to further reading and sources

We have now looked at a number of different graphs and charts, all of which were potentially misleading. We hope that from now on if you have to work with a graph or a chart, you will always consider the following points:

• look carefully at any horizontal or vertical scale that is given;

• consider each graph or chart separately, don't compare them unless you are sure that they have the same scales;

• if it is not easy to

We can use a number of different ways to indicate change – fractions, decimals, and percentages tend to be the ones with which many of us are familiar.

Some of the sentences we have looked at are harder to understand than they might be because they are not very well punctuated. Punctuation marks are the ‘stops’ in a sentence that divide it up into parts. They make it easier to follow the meaning of the words. For instance, it is easier to read this sentence of Philip's if we put a comma after ‘wealthy’:

With society becoming more wealthy, it was possible for t

Do you sometimes feel that you do not fully understand the way that numbers are presented in course materials, newspaper articles and other published material?

What do you consider are your main worries and concerns about your ability to understand and interpret graphs, charts and tables?

Spend a few minutes writing these down before you read on.

After studying this course, you should be able to:

• reflect on existing skills and mathematical history, set up strategies to cope with mathematics and assess which areas need improving

• understand the following mathematical concepts, through instruction, worked examples and practice activities: reflecting on mathematics; reading articles for mathematical information; making sense of data; interpreting graphs and charts

• draw on a technical glossary, p

Now we will look at the way Philip and Hansa wrote and presented their essays. Did you find them both easy to read? As regards Philip's, my answer is, ‘yes and no’. It is sometimes easy because he has a fluent way with words. But it is often difficult because he does not use enough punctuation to help us make sense of his words, and because of certain mistakes he makes. I found Hansa's essay easier to read. Her writing is more technically correct and more assured than Philip's. But

Although we live in a society where a huge amount of information is available in the form of numbers, some of us still feel a mental fog descend when we are asked to deal with them. This is because numerical information is information in a very condensed and abstract form. A number on its own means very little. You have to learn to read it. Numeracy (the ability to work with numbers) is a skill that we can learn. It is a very useful skill, because it allows us to understand very quickly the <

One of the main purposes of this course is to help you develop two kinds of skills:

• the general skills of being a student

• some skills which are particularly associated with the way social scientists work.

Both are of fundamental importance to your success in studying other courses. This course is about the very basic study skills of reading and taking notes. These are basic in the sense that they are the foundation for al

What distinguishes psychological research from common sense is that psychologists approach information and knowledge in a systematic and consciously articulated way. They use rules and procedures about how to build and apply theories, how to design studies to test hypotheses, how to collect data and use them as evidence, and how to evaluate all forms of knowledge. (See Figure 1, ‘The cycle of enquiry’ in Author(s): The Open University

A second kind of data is people's inner experiences, including their feelings, beliefs and motives. These cannot be directly seen from the outside; they remain private unless freely spoken about or expressed in some other way. Examples of these inner experiences include feelings, thoughts, images, representations, dreams, fantasies, beliefs and motivations or reasons. These are only accessible to others via verbal or written reports or as inferred from behaviours such as non-verbal communicat

If we look specifically at OpenLearn free courses, the content comprises both the course (structured self-study resources) as well as the individual assets that make up a course.

The assets of a course are the materials such as text, images, animations, audio clips, etc., which are likely to be in different digital formats. In some cases a course will consist of just one asset, but most contain a variety.

As the number of OpenLearn free courses grows, so does the variety available

When seeking content for adaptation and re-use in open educational contexts there are several tools available to support discovery. Many of these tools are the result of experimental prototyping and short-term funded projects, however, and therefore carry with them a certain amount of risk. Not all are sustained beyond the life of the funding, but these initiatives have sought to use a variety of search technologies to support the discovery of generic and domain-specific OERs.
