Welcome to the Euclid's Statistical Matrix! This is a Multiilingual Dashboard designed to assist in the teaching and learning of the basics of statistics. The Matrix includes 4 outstanding youtube courses and an excellent ebook by  David Lane. It is also multilingual with an Arabic Course by Dr. Serageldin and an Arabic RMLA. Videos from each series line up across the Matrix rows based on similar video content so that if a student or teacher has difficulty with lecture on hypothesis testing video, they can look at videos on the same topic from other instructors. Each cell contains hyperlinks which will take you to the video lecture on the YouTube website. If one has difficulty understanding a statistical concept in class, they may try one or more of the following videos in the grid! Also, this greatly helps the preparation of statistics courses as one can see 6 or more different ways that others have taught.

   Agriculture Statistics Matrix   Anthropology Statistics Matrix   Statistics Matrix in Arabic   Statistics Matrix in English   Farsi Statistics Matrix   Japanese Statistics Matrix   Psychology Statistics Matrix   Russian Statistics Matrix   Sociology Statistics Matrix

The first column of the Matrix has been left empty; this allows for individual adaptation of the Matrix, where a lecturer may insert their own lecture materials (video, powerpoint, etc.). Enjoy!    Contact Us - supercoursehelp@gmail.com

Khan Academy (khanacademy.org) is a non-profit organization which utilizes a computerized blackboard to illustrate each step of a problem. "Our mission to provide a world-class education for anyone, anywhere."

Brandon Foltz has a masters in Education and a passion for sharing knowledge. "My videos are full-length lessons...so grab some coffee, tea, lassi, Apokat, sbiten', soo chunkwa...or whatever sounds tasty and relaxing." 

These series of YouTube videos are brought to you by StatisticsLectures.com. "We focus on creating short, applied content with an emphasis on the logic behind various statistical methods."

David Longstreet from MyBookSucks.com expertly takes you through several statistical concepts.   "The goal is to use 21st century tools to deliver education and learning for statistics."

David Lane is the principal developer of this resource although many others have made substantial contributions. This site was developed at Rice University, University of Houston-Clear Lake, and Tufts University.
