Math Forum Problems of the Week | SISA Statistical Analysis |
VisAble Calculator MATH FORUM PROBLEMS OF THE WEEK (POWS) After a summer hiatus, the Math Forum's Problems of the Week, designed to provide creative, non-routine challenges for students in grades 3-12, have resumed for the 1999-2000 school year. This year we will be hosting six problems: - Elementary - Middle School - Geometry - Algebra - Discrete Math - Trig & Calculus As our project grows, we need more adult mentors to reply to students. Please consider joining our volunteer cavalry mentor group, whose members send replies to a few students each week. For more information, choose a level or topic and follow its Mentor Project link; to read about how students can participate, follow the link to a Current Problem, then select Information and Guidelines, or Rules, or Frequently Asked Questions. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- SISA: SIMPLE INTERACTIVE STATISTICAL ANALYSIS Daan Uitenbroek A collection of procedures for performing simple statistical calculations online, using HTML Forms. SISA's statistical tools include: - statistical procedures: sequential probability, ratios, t-test, Fisher exact, two by two table, ordinal tests, pairwise - discrete distributions: Poisson, binomial, hypergeometric, negative binomial - calculations: Bonferroni, random numbers, response rates, sample size, significance testing, simple, power Help documentation, MS-DOS programs, free life table spreadsheets, conference listings, literature (Medline) searches, government statistics bureaus, and other links are also provided. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- VisAble LARGE DISPLAY SCIENTIFIC CALCULATOR A calculator designed by the University of Waterloo's Centre for Sight Enhancement that allows low-visioned users to perform scientific, statistical, and trigonometric calculations. Focus groups were used to determine the functionality and visibility requisites for each feature of the calculator, including its display, keypad, and instruction manual. Includes all basic scientific and mathematical functions.
