Every month we will give you a math/statistics brain teaser that lets you test your knowledge with a fun problem.Many of the ideas in these Teasers come from thoughts formed by some of the great mathematical/statistical geniuses in history.
Real Remote Mass Spring Laboratory Experiments across InternetInherent Part of Integrated E-Learni
The paper presents the application of Integrated e- Learning, presented in general terms at this conference , exemplified on one of the most important parts of Physics - the thematic block Oscillations. The goal of the course of Physics in the chapter of Oscillations is to show the oscillatory movement as a basis of nearly all natural phenomena. The unifying model for all real world systems then may be the mass-spring system constituting the mechanical oscillator. The three constituting c
RobertNiles.com: Statistics Every Writer Should Know
Robert Niles, a journalist and producer for the LA Times, created this site to help other writers learn the basics of statistics. He explains many key concepts that are essential to report accurate, meaningful numbers and facts. After starting with the fundamentals of mean, median, and percent, Niles goes on to describe more advanced topics like normal distribution, margin of error, and data analysis. For each section, an example or two are provided to demonstrate proper usage of the techniques.
This course introduces students to the basic concepts, logic, and issues involved in statistical reasoning. Major topics include exploratory data analysis, an introduction to research methods, probability, and statistical inference. The objectives of this course are to give students confidence in manipulating and drawing conclusions from data and provide them with a critical framework for evaluating study designs and results. An important feature of the course is the use of an intelligent tutori
Empirical Research Methods
Regression analysis is an enormously popular and powerful tool, used ubiquitously in the social and behavioral sciences. Most courses on the subject immediately dive into the mathematical aspects of the subject and illustrate the technique on problems that are already highly structured. As a result, most students come away with little idea of the wide range of problems to which regression analysis can be applied and how to represent those problems in a way that cleverly utilizes readily availabl
Does excessive exposure to violent video games cause violent behavior? Does increased gun availability cause more crime or less? Causal claims permeate everyday life and are constantly the subject of "studies" reported in the newspaper. The material in Causal and Statistical Reasoning examines the nature of causal claims and the statistical sorts of evidence used to support them. The material is contained in: approximately 20 content modules, a repository of over 100 short case studies, and a "C
TALAT Lecture 2401: Fatigue Behaviour and Analysis
This lecture explains why, when and where fatigue problems may arise and the special significance to aluminium as structural material; it helps to understand the effects of material and loading parameters on fatigue; to appreciate the statistical nature of fatigue and its importance in data analysis, evaluation and use; it shows how to estimate fatigue life under service conditions of time-dependent, variable amplitude loading; how to estimate stresses acting in notches and welds with conceptual
Arrival of the Twenty-Second Indiana Volunteers
The soldiers are leaving the steamboat City of Alton and walking into St. Louis. Church steeples are in the background. A rowboat is on the shore with two men standing near it. The article says the sketch was made by one of the soldiers, and an excerpt from his accompanying letter is in the article. He says the regiment was in North Madison until August 14, 1861 when they received orders to proceed to St. Louis via Indianapolis. At the Mississippi River they boarded the steamboat City of Alton a
How to conduct a literature search
This resource show you how to conduct a basic literature search including the use of bollean operators - and and or to refine searches
Poverty and Elimination of Urban Health Disparities Challenge and Opportunity
The aim of this article is to examine the intersection of race and poverty, two critical factors fueling persistent racial and ethnic health disparities among urban populations. From the morass of social determinants that shape the health of racial and ethnic communities in our urban centers, we will offer promising practices and potential solutions to eliminating racial and ethnic health disparities.
The effects of explicit teaching of morphemic analysis on vocabulary learning and comprehension and
This study investigated the effects of explicit teaching of morphemic analysis on vocabulary learning and comprehension and its transfer effects to novel words with sixth grade students. Because research states that vocabulary and the ability to decode unfamiliar words is vital for comprehension, an increase in vocabulary learning and comprehension was predicted. A sixth-grade reading class with low reading assessment results was specifically taught twelve affixes and roots chosen from a bank of
Where is Mr. Clean? Household division of labor and the pay gap between men and women
The household division of labor and the pay gap between men and women is examined using the 2003 American Time Use Survey. There are three components to an income determination model: individual, structural and gender level components. The individual component argues that people are rational human beings who make conscious decisions on how to maximize their utility, with increased investments in human capital possibly leading to increases in income. The structural component views society as orga
The effects of activating prior knowledge before reading on students with and without learning disab
Students with learning disabilities use prior knowledge differently than students without learning disabilities. This paper examines what happens to reading fluency, words per minute, and reading comprehension when prior knowledge is activated. By using two reading passages at the fourth grade level, students read one passage without prior knowledge activation and another with prior knowledge activation. The students were timed for words per minute. The reading errors were noted for fluency, and
The consequences of antisocial behavior in older male siblings for younger brothers and sisters
The contribution of younger male and female siblings’ conflict and involvement in deviant activities with their older brothers to younger siblings’ adolescent adjustment problems was examined in the context of parenting. Ineffective parenting during younger siblings’ childhood had no direct effects on adjustment, but facilitated their exposure to older brothers’ deviant peers and activities. The effect of sibling conflict on adjustment was mediated by younger siblings’ co-participation
2.830J Control of Manufacturing Processes (SMA 6303) (MIT)
This course explores statistical modeling and control in manufacturing processes. Topics include the use of experimental design and response surface modeling to understand manufacturing process physics, as well as defect and parametric yield modeling and optimization. Various forms of process control, including statistical process control, run by run and adaptive control, and real-time feedback control, are covered. Application contexts include semiconductor manufacturing, conventional metal and
Discovering Diversity - Taffye
Taffye, associate provost of equity, diversity and community relations discusses the importance of inclusion and diversity on campus and the role that the Office of Equity, Diversity and Community Relations plays at ECU
18.443 Statistics for Applications (MIT)
This course offers a broad treatment of statistics, concentrating on specific statistical techniques used in science and industry. Topics include: hypothesis testing and estimation, confidence intervals, chi-square tests, nonparametric statistics, analysis of variance, regression, and correlation. OCW offers an earlier version of this course, from Fall 2003. This newer version focuses less on estimation theory and more on multiple linear regression models. In addition, a number of Matlab example

Working with charts, graphs and tables
Your course might not include any maths or technical content but, at some point during your course, it’s likely that you’ll come across information represented in charts, graphs and tables. You’ll be expected to know how to interpret this information. This unit will help you to develop the skills you need to do this. This unit can be used in conjunction with the ‘More working with charts, graphs and tables’ unit, which looks into more ways to present statistical information and shows y
