7.1 Introduction

Charts, graphs and tables are all very helpful ways of representing a set of data. However, they are not the only ways of passing on information about data. This section looks at how you can analyse a set of data to summarise the given information as briefly and simply as possible.

Essentially, there are two features of a set of data that enable summarising: the average and the spread. This section starts by looking at what is meant by â€˜averageâ€™. If you have already studied OpenL

3.2 Necessities and luxuries

As the division of opinion between the government and low income people illustrates, definitions of poverty are the stuff of political debate. People in the Rowntree studies tended to focus on â€˜paying bills and foodâ€™. Most people's list of basic needs would also include adequate food and clean water, clothing, shelter and heating. But are there also less apparently physiological, more evidently social, necessities of life?

5.2.2 Continuous variables

Not all numbers are discrete. Consider the following measurements:

• times to run a marathon

• temperatures recorded at intervals during a day

• weight of each bunch of grapes sold at a supermarket yesterday.

Time, temperature and weight are all examples of numerical data, but there is not a restricted set of values that they can take. Whereas you can have 2 or 3 children in a family but not 2.5, with tempe

Review of Slope-Intercept Form
Instructor uses a white board to review the concept of Slope-Intercept Form.Â  Examples include creating an equation given a slope and a point.Â

Point-Slope Form
This video explains how to use point-slope form when writing a linear equation. Point-slope form can be written using one point and the slope or when given two points since we can calculate the slope from the two points. Once we have an equation in point-slope form, it can be rewritten in slope-intercept or standard form. (1:12)

Compressive and tensile deformation in bubble raft
Bubble raft undergoing compressive and tensile deformation. At small strains, the arrangement of the bubbles does not change. This is elastic deformation of the raft. The bubbles change shape and move slightly apart in an effort to maintain the lowest energy close-packed configuration. At larger strains, plastic deformation occurs. The bubble raft rearranges by dislocation motion. From TLP: Introduction to dislocations, http://www.msm.cam.ac.uk/doitpoms/tlplib/dislocations/dislocation_motion.php

3.22 Division rules

Lastly consider division. Dividing 8 by 2 means â€˜How many times does 2 go into 8?â€™ or â€˜What must you multiply 2 by to get 8?â€™. The answer is 4.

So to find 8 Ã· âˆ’2, you need to ask â€˜What do I have to multiply âˆ’2 by to get 8?â€™. The answer is âˆ’4, since âˆ’2 Ã— âˆ’4 = 8.

So 8 Ã· âˆ’2 = âˆ’4.

Similarly, to find âˆ’8 Ã· âˆ’2 you need to ask â€˜what do I have to mul

Setting Up a Chemistry Experiment to Test Ph of Acids & Bases
Setting Up a Chemistry Experiment to Test Ph of Acids &amp; Bases. Part of the series: Chemistry Lesson: Ph Tests for Acids &amp; Bases. When conducting a chemistry experiment on the acid level of various household substances, begin with a hypothesis on whether or not a substance is acid-based. This two minute video goes rapidly and students would benefit from a word wall and to have the experiment in front of them to practice after the video is shown.

4.4 Historical note on the Euler characteristic

A little history is instructive here, because it shows how difficult Theorem 9 really is. By 1900 the classification of compact surfaces was well understood, although proofs of the major theorems relied more on intuition than would be acceptable today. Attention switched to objects called â€˜3-manifoldsâ€™, topological s

Shirley Temple reciting poetry by Rose Fyleman
From the 1935 film Curly Top. Elizabeth (Shirley Temple) recites two short poems for her uncle Edward (John Boles). The first poem, "Before," was published in Punch magazine in 1919, with the author named simply as "R.F." -- probably Rose Fyleman, a British children's poet who also wrote the second poem Shirley recites, entitled "Singing-Time."

Nature by Numbers
A movie inspired by numbers, geometry, and nature. Music helps sets the tone. A great way to get students interested in geometry and see it in nature. Would be a great start to a research project or sharing ideas of other examples. (03:44)

Le Corbusier: Modernist Originality or Copying?
While describing the genius of his originality and his â€˜intuitive flashes of insightâ€™, Le Corbusier systematically obliterated unwanted references from the works of his biographers and set up a carefully vetted archive called the Le Corbusier Foundation. This lecture considers the discovery of a recently discovered handwritten entry in a â€˜lostâ€™ (ie thrown away) Le Corbusier notebook, which indicates that he found (more than) inspiration in the work of a relatively forgotten modernist ar

4.4 O is for Objectivity

One of the characteristics of 'good' information is that it should be balanced and present both sides of an argument or issue. This way the reader is left to weigh up the evidence and make a decision. In reality, we recognise that no information is truly objective.

This means that the onus is on you, the reader, to develop a critical awareness of the positions represented in what you read, and to take account of this when you interpret the information. In some cases, authors may be e
