Students will analyze the 1950 Census form for Americans living overseas and 1910–1990 census data for these Americans to understand the impact of the Cold War on the number of U.S. citizens living abroad.
Students will explore census data, including infographics and reports, to better understand rates of poverty in the nation.
The applets in this section of Statistical Java address Power. Users can perform one or two tailed tests for proportions or means for one or two samples. Set the parameters and drag the mouse across the graph to see how effect size affects power.
In this lesson is colected four practical exercises about probability. Lesson is ready to use, but teachers should be prepared to add some extra information about this topic befor doing the lesson.
These practice tests from MIT OpenCourseWare cover topics in the Introductory Probability and Statistics course. They were originally written by Professors Jeremy Orloff and Jonathan Bloom, and adapted by the team at OpenStax CreatorFest. The files include both assessments and solutions.
As densely populated urban areas continue to expand, human activity is removing much-needed greenspaces from our communities; in turn, we are also removing critical buffers that are needed to combat air and water pollution, leaving cities vulnerable to a variety of health issues and potential infrastructure damage. In August of 2017, the Greater Houston area experienced a catastrophic flooding event, with Hurricane Harvey being designated as the wettest tropical cyclone ever recorded in US history. With many areas receiving 40" or more of rain, the rising flood waters had nowhere to go in a city covered in concrete, a barrier to natural infiltration. This caused over $125 billion in damage, with flood waters inundating hundreds of thousands of homes and displacing more than 30,000 people. In 2018, Katy High School responded by restoring an acre of public campus property to native Texas Gulf Coast prairie. The prairie will ultimately serve as an outdoor classroom for students, a greenspace for community outreach, and also as a natural retention area for future flooding events. Urban greenspaces, like the KHS Tiger Prairie, are mini-ecosystems that can potentially mitigate billions of dollars in flood damages while conserving precious habitats for native species; these pocket prairies not only model of conservation best-practices, but they also provide multiple, quantifiable ecoservices to communities. The KHS Tiger prairie will serve as a model for this activity, allowing students the opportunity to calculate the quantifiable cost-savings of incorporating native landscapes in their communities. Students will analyze recent precipitation and infiltration data, make predictions on which locations in urban areas have the most potential for restoration, and reflect on the societal and economic barriers to current conservation efforts.
In order to give Introductory Geology (Physical Geology) undergraduate non-majors students experience and confidence in using basic algebra to calculate very simple stream flow properties, we use a prework assignment prior to the Rivers and Streams Lab. Prework is a worksheet assigned 2 weeks in advance, which asks students to calculate velocity and discharge as well as unit conversions and calculations of stream load. The questions are put into the context of activities they completed earlier in the semester during visits to the stream (on campus) so questions are relevant to their previous experiences. The prework timeframe gives students the opportunity to seek extra help from their instructor prior to the lab period in which they will make additional measurements, similar calcualations and interpretations of their data.

You are probably asking yourself the question, "When and where will I use statistics?". If you read any newspaper or watch television, or use the Internet, you will see statistical information. There are statistics about crime, sports, education, politics, and real estate. Typically, when you read a newspaper article or watch a news program on television, you are given sample information. With this information, you may make a decision about the correctness of a statement, claim, or "fact." Statistical methods can help you make the "best educated guess."
Epidemiology for Non epidemiologists
Short Description:
Although there are several principles of epidemiology textbooks, there is need to have a textbook that is tailored mainly to undergraduates, and this is that book.

Examples finding probabilities from probability distributions for continuous random variables.
In this class, students will be able to identify what is probability and have a general concept. The students should be able to calculate the probability questions by using the formula of conditional probability (P( A|B )=number of A/the total number of outcomes.)
The addition rule for probability is explained using Venn Diagrams. [Probability playlist: Lesson 3 of 29]
Students will begin to think about probability by considering how likely it is that their house will be struck by lightning. They will consider the relative likelihood of familiar events (e.g., outdoor temperature, test scores) on the continuum between impossible and certain. Students will discuss where on the continuum "likely," "unlikely," and "equally likely as unlikely" areGoals and Learning ObjectivesThink about the concept of likelihood.Understand that probability is a measure of likelihood.Informally estimate the likelihood of certain events.Begin to think about why one event is more likely than another.SWD: Students with disabilities may need additional support seeing the relationships among problems and strategies. Throughout this unit, keep anchor charts available and visible to assist them in making connections and working toward mastery. Provide explicit think alouds comparing strategies and making connections. In addition, ask probing questions to get students to articulate how a peer solved the problem or how one strategy or visual representation is connected or related to another.

This page of Statistical Java describes 11 different probability distributions including the Binomial, Poisson, Negative Binomial, Geometric, T, Chi-squared, Gamma, Weibull, Log-Normal, Beta, and F. Each distribution has its own applet.
MCQ questions on Probability
Today we’re going to begin our discussion of probability. We’ll talk about how the addition (OR) rule, the multiplication (AND) rule, and conditional probabilities help us figure out the likelihood of sequences of events happening - from optimizing your chances of having a great night out with friends to seeing Cole Sprouse at IHop!
