This text manual introduces statistical analysis and its underlying philosophy, enabling students to understand how to describe the confidence they have in their analysis. Statistical analysis is one of the most widely used, and abused, techniques in the biological sciences. Statistics are ostensibly used to allow an investigator to be objective. That is, the researcher uses statistical tests to determine whether or not his/her hypothesis is supported by the data collected. Unfortunately, the
Bioenergetics: Energy flow, secondary production, and ecological efficiencies of Madagascan cockroac
This lab exercise tests the ecological principle of energy flow in a laboratory setting using roaches as an experimental secondary producer. Energy use is measured by respiration, energy storage by growth, and energy input as ingestion minus feces. The laws of thermodynamics state that energy intake should equal energy output; accuracy of measurements can therefore be determined. Growth rates, respiratory rates, and ingestion rates can be compared for different size classes. The exercise lasts f
Statistical Reasoning I
Statistical Reasoning in Public Health provides an introduction to selected important topics in biostatistical concepts and reasoning through lectures, exercises, and bulletin board discussions. It represents an introduction to the field and provides a survey of data and data types. Specific topics include tools for describing central tendency and variability in data; methods for performing inference on population means and proportions via sample data; statistical hypothesis testing and its appl
Peirce And Fisher on the Place of Probability in Abductive Inference
In his analysis of inference into three types, deduction, induction, and abduction, C. S. Peirce maintains that probability plays an essential role in the first two, but not in the third. For a deductive argument, probability tells us the frequency with which the conclusion will hold given the premises; for an inductive argument, probability tells us the frequency with which the argument will hold true. However, probability has no role to play in abduction because there is, in Peirce's view, no
Epidemiological Thinking For Non-Specialists, Fall 2007
Introduction to methods and problems in research and applications where quantitative data is analyzed to reconstruct possible pathways of development of behaviors and diseases. Special attention given to social inequalities, changes over the life course, heterogeneous pathways, and controversies with implications for policy and practice. Case studies and course projects are shaped to accommodate students with interests in fields related to health, gerontology, education, psychology, sociology, a
Introduction to Applied Statistics, Summer 2003
This course provides graduate students in the sciences with an intensive introduction to applied statistics. Topics include descriptive statistics, probability, non-parametric methods, estimation methods, hypothesis testing, correlation and linear regression, simulation, and robustness considerations. Calculations will be done using handheld calculators and the Minitab Statistical Computer Software.
Statistics - an intuitive introduction : standard deviation
A standard way of measuring statistical variability: standard deviation and the associated concepts of variance and degrees of freedom.
15.075 Applied Statistics (MIT)
This course is an introduction to applied statistics and data analysis. Topics include collecting and exploring data, basic inference, simple and multiple linear regression, analysis of variance, nonparametric methods, and statistical computing. It is not a course in mathematical statistics, but provides a balance between statistical theory and application. Prerequisites are calculus, probability, and linear algebra. We would like to acknowledge the contributions that Prof. Roy Welsch (MIT), Pro
Seymour Hersh: Mario Savio Memorial Lecture
One of America's premier investigative journalists, Seymour Hersh shocked the world with his expose of the military's treatment of prisoners at Abu Ghraib. His revelation of the My Lai massacre and its cover-up during the Vietnam War won the Pulitzer Prize for international reporting. He writes regularly for The New Yorker on military and security matters and is the author of many books. The 9th Annual Mario Savio Memorial Lecture & Young Activist Award is presented annually to honor the memory
2.57 Nano-to-Macro Transport Processes (MIT)
This course provides parallel treatments of photons, electrons, phonons, and molecules as energy carriers, aiming at fundamental understanding and descriptive tools for energy and heat transport processes from nanoscale continuously to macroscale. Topics include the energy levels, the statistical behavior and internal energy, energy transport in the forms of waves and particles, scattering and heat generation processes, Boltzmann equation and derivation of classical laws, deviation from classica
6.041 Probabilistic Systems Analysis and Applied Probability (MIT)
This course is offered both to undergraduates (6.041) and graduates (6.431), but the assignments differ. 6.041/6.431 introduces students to the modeling, quantification, and analysis of uncertainty. Topics covered include: formulation and solution in sample space, random variables, transform techniques, simple random processes and their probability distributions, Markov processes, limit theorems, and elements of statistical inference.

The new face of bling in China -- bikes
Jan. 14 - Ultra high-end models are challenging the bicycle's working-class image in China, and giving posh cars a run for their money as the latest status symbol for the country's nouveau riche.
20.109 Laboratory Fundamentals in Biological Engineering (MIT)
This course introduces experimental biochemical and molecular techniques from a quantitative engineering perspective. Rigorous quantitative data collection, statistical analysis, and conceptual understanding of instrumentation design and application form the underpinnings of this course. The four discovery based modules include DNA Engineering, Protein Engineering, Systems Engineering, and Biomaterials Engineering. Additional information is available on the course Wiki (hosted on OpenWetWare.) T
8.044 Statistical Physics I (MIT)
This course offers an introduction to probability, statistical mechanics, and thermodynamics. Numerous examples are used to illustrate a wide variety of physical phenomena such as magnetism, polyatomic gases, thermal radiation, electrons in solids, and noise in electronic devices.
5.72 Statistical Mechanics (MIT)
This course discusses the principles and methods of statistical mechanics. Topics covered include classical and quantum statistics, grand ensembles, fluctuations, molecular distribution functions, other concepts in equilibrium statistical mechanics, and topics in thermodynamics and statistical mechanics of irreversible processes.
Biodiversity Consortium : Measuring Ecological Diversity 3 : Measuring Abundance and Diversity
This package looks at how you measure ecological diversity at the regional level, and tackles more general questions relatinv to the various diversity indices and abundance models available. This package looks at species richness, relative abundance plots, diversity indices as well as covering such issues as sampling effort and the practical implications of using these statistical tests in applied ecology.

8.811, Particle Physics II, describes essential research in High Energy Physics. We derive the Standard Model (SM) first using a bottom up method based on Unitarity, in addition to the usual top down method using SU3xSU2xU1. We describe and analyze several classical experiments, which established the SM, as examples on how to design experiments. Further topics include heavy flavor physics, high-precision tests of the Standard Model, neutrino oscillations, searches for new phenomena (compositenes

Statistical data have a tendency to cluster around some central point. How do we determine this point? Is there just one way of doing it or more than one?
