  ### MIDDLE GROUND

 Welcome,     For a long page that's designed for someone with an 8th grade math background, heavy on vocabulary, light on computation, but no counting theory go to A Year of Statistics in an Hour or Two.     For just the vocabulary from "A Year of Statistics in an Hour or Two" go to Statistics Vocabulary.     For statistics resources stay on this page, MIDDLE GROUND, the statistics info page.

 Computation Resources & Probability in Calc I statsc.xls - a spread sheet that computes means, standard deviations,     z-scores, and probabilities, expected values stat.xls - a spread sheet completed computes needed for hypothesis tests  ReimannSums.gsp - Reimann Sums & Boxes - See sheet "cum" for     p(a < x < b ) graphically and computationally. prob4calc.htm - Probabilitity for Calc I - Area Under A Normal Curve,     Cumulative Probability, probability facts a calc I student should know

 Descriptive Statistics A Statistic is a Description- average, center, range, standard deviation, spread, number line The "Spread" Lab The "General Shapes" Lab

 Normal Distributions Some Features of A Normal Distribution - bell curve, symmetry, mean-mode-median, distribution of scores, area in an interval, probabilities Normal Distributions - area under the curve, traditional z-score & probability table, probability notation & problems The Standard Normal Distribution - mean of 0, standard deviation of 1, z-score, x-score, interval and number line, probabilities in a interval Answers to Normal Distribution Problems  Stanines - Standard Nine Intervals in Testing & Education, areas in the intervals, descriptive names for values in the intervals, probabilities, problems   6 Sigma - Six Sigma Standards and Ordinary Statistics, the method uses the statistics

 Binomial Distributions

 Testing Confience Interval - range of expected values Hypothesis Testing - make a judgement based on a statistically analyzed situation HYPOTHESIS TESTS - different tests and their parameters HYPOTHESIS TESTS pdf file video about the HYPOTHESIS TESTS pdf file, yes, a video about a pdf file, filed with other videos
