Take College And University Courses Online Completely Free In recent years massive open online courses (MOOCs) have become a trend in online education. The term was coined in 2008 by David Cormier, manager of web communications and innovations at the University of Prince Edward Island. The first MOOC was created the previous year, at Utah State University. Today, there are hundreds of thousands of courses available online at no cost. You can study anything from business to zoology in your own home at no cost. MOOCs are designed like college courses but are available to anyone anywhere in the world, at no cost. Coursera is perhaps the most well-known of the online education facilitators. EdX is another non-profit course site created by founding partners Harvard and MIT and based in Cambridge, Massachusetts. MIT has their own open courseware, where most of the materials used in the teaching of almost all of MIT's subjects are available on the Web, free of charge. European institutions are also getting in on the act.

About The third is community. We believe learning should be as rich and varied as the world you're learning about. So with our community we're building a kind of multimedia wonderland of learning, where videos, audio, usage, mnemonics, etymologies and much more bring your learning to life. We believe that every learner is partly a teacher, and we hope that once you get started, you'll soon be supplying little nuggets of wit and wisdom to help the rest of the community as they learn! Anyone can learn anything We believe that learning’s quite simple, and that there’s nothing that can’t be learned with the right help and enthusiasm. Together we are smarter Millions of people have learned what you want to learn. As you learn, you share your ideas to help others, just as you benefit all the time from the ideas other people have shared. This way, we all learn quicker and more effortlessly. Play works We’re at our most receptive when we’re at play. Your memory is a garden, not a storehouse

Fisher's exact test of independence - Handbook of Biological Statistics Summary Use the Fisher's exact test of independence when you have two nominal variables and you want to see whether the proportions of one variable are different depending on the value of the other variable. Use it when the sample size is small. When to use it Use Fisher's exact test when you have two nominal variables. A data set like this is often called an "R×C table," where R is the number of rows and C is the number of columns. Fisher's exact test is more accurate than the chi-square test or G–test of independence when the expected numbers are small. Null hypothesis The null hypothesis is that the relative proportions of one variable are independent of the second variable; in other words, the proportions at one variable are the same for different values of the second variable. How the test works Next you calculate the probability of more extreme ways of distributing the 12 sick people: Post-hoc tests Assumptions Independence Fixed totals Examples Graphing the results Similar tests Web pages

Ciência em Três - recursos de ciência para escolas (BI) Banco de imagens para exposição da Cavalariça Stanford Encyclopedia of Philosophy Philosophy Philosophy is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language.[1][2] The Ancient Greek word philosophia was probably coined by Pythagoras[3] and literally means "love of wisdom".[4][5][6][7][8] In the 19th century, philosophy became more professionalized as it began to be studied and taught in modern research universities.[13][14] Contemporary academic philosophers subdivide research areas in various ways. For example, topical divisions include major branches such as epistemology, logic, metaphysics, ethics, aesthetics, and other specialized branches. Other ways of dividing include historical period (e.g., ancient and modern); thinker (e.g., Platonism, Confucianism, Kantianism); or philosophical tradition (e.g., analytic or Continental). Many of these recurring questions are still debated in philosophy and other fields today. Etymology Areas of inquiry Philosophy has been subdivided in various ways. Logic
