Each of the links will show an annotated list of the statistical procedures available under that rubric. There is a great variety of online statistical ’tools’ or applets that are ready to use and include: Utilities, Clinical Research Calculators, Probabilities, Distributions, Frequency Data, Proportions, Ordinal Data, Correlation and Regression, t-Tests and Procedures, ANOVA, ANCOVA, and Miscellanea. http://www.merlot.org/merlot/viewMaterial.htm?id=280904 GeoGebra is a dynamic mathematics software for education in secondary schools that joins geometry, algebra and calculus. On the one hand, GeoGebra is a dynamic geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards.On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum.The GeoGebraWiki is a free pool of educational materials for GeoGebra. Everyone can contribute and upload materials there: International GeoGebraWiki - pool of educational materials for GeoGebra and the German GeoGebraWiki The Dynamic Worksheets GeoGebra can also be used to create dynamic worksheets:Pythagorasvisualisation of Pythagoras' theoremLadder against the Wallapplication of Pythagoras' theorem Circle and its Equationconnection between a circle's center, radius and equation Slope and Derivative of a Function (3 sheets)relation between slope, derivative and local extrema of a functionDerivative of a Polynomial interactive exercise to practice finding the derivative of a cubic polynomialUpper- and Lower Sums of a Functionvisualisation of the backgrounds of Riemann's Integral http://www.merlot.org/merlot/viewMaterial.htm?id=316569 This website is for people involved in applied social research and evaluation. You'll find lots of resources and links to other locations on the Web that deal in applied social research methods.Some highlights of what is available: The Knowledge Base, Selecting Statistics, The Simulation Book, Concept Mapping http://www.merlot.org/merlot/viewMaterial.htm?id=280883 Math Maze is not a typical math site which may be helpful for math worksheets. The main purpose of building this site is to make more and more people love math. http://www.merlot.org/merlot/viewMaterial.htm?id=315076 Möbius Transformations Revealed is a short video by Douglas Arnold and Jonathan Rogness which depicts the beauty of Möbius transformations and shows how moving to a higher dimension reveals their essential unity. It was one of the winners in the 2007 Science and Visualization Challenge and was featured along with the other winning entries in the September 28, 2007 issue of journal Science. The video, which was first released on YouTube in June 2007, has been watched there by more than a million viewers and classified as a "Top Favorite of All Time" first in the Film & Animation category and later in the Education category. It has been selected for inclusion in MathFilm Festival 2008. http://www.merlot.org/merlot/viewMaterial.htm?id=346931 Studycasts are designed to support the academic work taking place in Harrison High School classrooms. These Studycasts can include unit summaries, test reviews, and other academic support materials. http://www.merlot.org/merlot/viewMaterial.htm?id=236900 R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control. R is available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS.
