4.7: Quartiles and the interquartile range The first alternative measure of dispersion we shall discuss is the interquartile range: this is the difference between summary measures known as the lower and upper quartiles. The quartiles are simple in concept: if the median is regarded as the middle data point, so that it splits the data in half, the quartiles similarly split the data into quarters. This is, of course, an over-simplification. With an even number of data points, the median is defined to be the average of the middle two: de
Finding the Hypotenuse
The hypotenuse of a right triangle is the side that is opposite of its right angle. Sometimes we have problems that ask us to find the missing hypotenuse of a right triangle. This video describes how to use the Pythagorean theorem to find the hypotenuse, but only when the length measure of the two legs is known. (1:16)
Young melanoma patient shares positive outlook on treatment
By: mdanderson Brian Rose, a young adult malignant melanoma patient at MD Anderson, does not advise studying your cancer's statistics. Rose says, "If you see your name in those statistics, go ahead and believe it. Until you see your name on one of those studies it really means nothing." It's important to be surrounded by a team of family, friends and physicians that share your focus and do not be afraid to reach out for help.
Workshop 8: Bend and Stretch
We all expect a spring to stretch or compress when a force is applied, but forces can even deform solid objects like the floor or the top of a table. In this workshop, students in a high school classroom explore ideas about tension and normal force. By applying a force to a spring and measuring the distance the spring is stretched, the students calculate the force consta
Patent Search How To
This is a simple, three minute video tutorial - training on using the www.uspto.gov site for a simple patent search. Would be interesting for students to see how the process works and also to check on patents given to people such as Edision. Great for added depth to invention and simple machine lessons.
Conclusion This free course provided an introduction to studying Education, Childhood & Youth qualifications. 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.
4.3.2 Removal of CO Under fuel-lean conditions (excess O2), the oxidation of CO has been studied over a very large range of single crystals and model noble metal catalysts, one of the most intensively investigated examples being the Pd(111) surface. Although this metal is not a component of the current three-way catalyst used in the UK, it is worth considering the results in some detail for a number of reasons. The reaction on metals such as Pt is in many ways similar to that on Pd and, in any

Duct Tape Crafts: Duct Tape School Folder and Notebook
This 3:40 long video slowly shows students how to use a variety of colored rolls of duct tape into usable school notebooks. This would be an expensive project and the tape does easily stick to practically anything, so this requires patience and good coordination.
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 ‘paying bills and food’. 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? The Science Behind Self-Control Joichi Ito: Enabling Emergent Voices and Expression through Technology Learning about Maps with Curious George Berlin 1961: Kennedy, Khrushchev, and the most dangerous place on earth [Audio] 1.2.7 In praise of cheap offshore labour? Claims over the benefits of globalisation and the exploitation of cheap offshore labour generate strong feelings and, not surprisingly, divide opinion between those who favour the global marketplace and its detractors. The issue turns on whether the constant search for ever-cheaper manufacturing and service locations is seen as a good or a bad thing. It may appear odd, at first, to suggest that exploiting the poor of another country can, on any measure, be regarded as a good thing, but
Have you ever wondered why you can't bring yourself to choose the foods that are healthy over the ones you know are unhealthy? Researchers are not only trying to find out why, but what parts of the brain govern behaviors of self-control and how we can work to improve them. Ben Hayden is a neuroscientist and Assistant Professor of Brain and Cognitive Sciences at the University of Rochester. He offers his insights based upon his research and how it has the potential to apply not only to our choice

Respondent: Brendan Mcgetrick, Independent Writer & Designer (China)
Moore’s law and the Internet have dramatically reduced the cost of producing and distributing information. This has greatly lowered the cost of collaboration and has empowered a qualitatively different “public” to think, express, and act without, or in spite of, central authority. These changes and advanc

Speaker(s): Frederick Kempe | Kempe explores the war of nerves between the young, untested President Kennedy and the bombastic Soviet leader, as they squared off over the future of a divided city - and the world came to the brink of disaster. This event celebrates the publication of Kempe's new book Berlin 1961: Kennedy, Khruschev, and the Most Dangerous Place on Earth.
