## Statistics Focus

Statistics and Probability Simulations  Concepts: central tendency, mean, median, skew, least squares.  Concepts: sampling distribution, standard deviation, standard error, central limit theorem, mean, median, efficiency, fluctuation, skew, normal distribution.Concepts: confidence interval, mean, standard deviation.  Concepts: binomial distribution, normal distribution, central limit theorem, correction for continuity.  Concepts: binomial distribution, normal distribution, central limit theorem, confidence interval.  Concepts: Correlation, slope, standard error of the estimate, variance, restriction of range, proportion of variance explained. etc. Virtual Laboratories in Probability and Statistics   The goal of this project is to provide free, high quality, interactive, web-based resources for students and teachers of probability and statistics. Basically, our project consists of an integrated set of components that includes expository text, applets, data sets, biographical sketches, and an object library. Please read the Introduction for more information about the content, structure, mathematical prerequisites, and organization of the project.  Sites   (Also see:  Infographics

1. ASL (pronounced "dazzle") is an online library of and that illustrate the use of basic statistics methods. We hope to provide data from a wide variety of topics so that statistics teachers can find real-world examples that will be interesting to their students. Use DASL's powerful search engine to locate the story or datafile of interest.
2. Probability Resources     Particular resources may be found by either a Keyword Search or an Advanced Search. See these options up and to your left.

9.  This website was developed by fifth year students in the Mathematics Education program at the University of Virginia. The University of Virginia offers a five-year dual-degree (BA/MT) teacher education program. At the end of five years students graduate with a Bachelor of Arts in mathematics and a Master of Teaching degree. The students collaboratively worked together developing this website for their Masters thesis project in the spring semester of 2000.

14. R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS. To download R, please choose your preferred CRAN mirror.
15. RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. People use RANDOM.ORG for holding drawings, lotteries and sweepstakes, to drive games and gambling sites, for scientific applications and for art and music.Math Worksheet Site   With The Math Worksheet Site you can create an endless supply of printable math worksheets. The intuitive interface gives you the ability to easily customize each worksheet to target your student's specific needs. Every worksheet is created when you request it, so they are different every time.This way you can add the practice that your student needs to a curriculum you already like, or you can be freed from the constraints of a workbook or textbook that gives either too much or too little practice if you would rather direct the studies yourself.These worksheets are provided in PDF format. For those who have a slow internet connection or an older computer, we also provide these worksheets as printable web pages
16. CrunchBase is the free directory of technology companies, people, and investors that anyone can edit.  It is developed and maintained by TechCrunch with the support of the tech community and visitors like you. If you have any questions about CrunchBase or the data contained within, please feel free to contact us.  Currently, all additions and edits to CrunchBase go through an approval process before they are pushed live. We are working on ways that will allow users to make immediate changes to the site. Expect to see this type of functionality rolled out soon.
