No final do ano de 2019 apareceu o primeiro caso de COVID-19 na China e, pouco tempo depois, em 2020, foi decretada a situação de pandemia. Desde então, estamos nos deparando a todo momento com dados dispostos em tabelas e gráficos sobre o nível de contaminação, morte e recuperação por COVID-19. Essas informações chegam também às crianças através dos meios de comunicação, tornando importante que sejam debatidas com elas as causas e consequências da pandemia, incluindo a importância do isolamento social e campanhas de vacinação. A cartilha digital intitulada Aprendendo Estatística em Tempos de COVID-19, destaca a importância da Estatística no combate a uma situação pandêmica nas aulas de Matemática nos anos iniciais do ensino fundamental, utilizando tabelas e gráficos, informações reais sobre a taxa de contaminação da COVID-19 e dados sobre a campanha de vacinação no Brasil.

A case-study approach can be used to introduce students to the work that geologists do as environmental consultants. Data used by environmental consultants for a Brownfield site that is currently undergoing redevelopment in St. Paul, MN has been adapted for in-class study, either as a series of short exercises, or as part of a larger project.

Teachers will engage students in a discussion about what the Census Bureau does and what types of information it collects. Then students will read and annotate informational texts from the Census Bureau and work with a partner to answer questions about the texts. Students will also analyze an infographic of people with different professions to determine how each of those people might use the data gathered by the Census Bureau; students will be asked to use evidence from the infographic text to support their answers. Students will then complete a wireframe (similar to a graphic organizer) for an online resource about how census data can help their own community.

Students will analyze a variety of county-level census data, including on employment, technology, and transportation, in histograms to compare and contrast the shapes of their distributions and to interpret measures of center and spread in context.

This video talka about what is easily one of the most fundamental and profound concepts in statistics and maybe in all of mathematics. And that's the central limit theorem.

Students will learn about their state as they collect and organize business information using State Facts for Students, a U.S. Census Bureau data tool. Students have the opportunity to examine data about kids their age, as well as a variety of other facts selected to appeal to young students. Students will create a bar graph to represent how the numbers of selected business types have changed between 2010 and 2016.

Today we're going to start our two-part unit on data visualization. Up to this point we've discussed raw data - which are just numbers - but usually it's much more useful to represent this information with charts and graphs. There are two types of data we encounter, categorical and quantitative data, and they likewise require different types of visualizations. Today we'll focus on bar charts, pie charts, pictographs, and histograms and show you what they can and cannot tell us about their underlying data as well as some of the ways they can be misused to misinform.

This lesson centers around the How AI Works: Chatbots and Large Language Models video from the How AI Works video series. Watch this video first before exploring the lesson plan.
Large Language Models (LLMs) generate new text. The text LLMs generate looks like a human might have written it because large language models are built based on large bodies of text, such as Wikipedia. In this lesson, students learn what an LLM is and how it works, then use an LLM to co-create a text with AI. Finally, the class wraps up with a discussion about whether or not LLMs are intelligent or creative.
This lesson can be taught on its own, or as part of a 7-lesson sequence on How AI Works. Duration: 45 minutes

The purpose of this assignment is for students to synthesize field observations, petrography, and whole-rock chemical analyses in order to investigate chemical differentiation processes in a basaltic magma chamber. The students first complete a petrography lab on both hand samples and thin sections that represent a complete stratigraphic section through sill at Fort Lee, NJ. I then provide them with major- and trace-element data and a table of distribution coefficients for common phases that would be crystallizing from basaltic magma. I then ask them to discuss the chemical differentiation of the sill by writing up a 1-2 page interpretative summary based on their petrographic observations and the chemical data.

Today we're going to talk about Chi-Square Tests - which allow us to measure differences in strictly categorical data like hair color, dog breed, or academic degree. We'll cover the three main Chi-Square tests: goodness of fit test, test of independence, and test of homogeneity. And explain how we can use each of these tests to make comparisons.

An introduction and examples of how to use the Chi square test. The test is used when analyzing assocation between two categorical variables and when comparing proportions. The idea behind the test is to compare the observed frequencies with the expected frequencies, if the two variables are unrelated.

Living in a big city like New York can be very challenging. City planning is an interdisciplinary enterprise where social scientists, humanists, psychologists, scientists, statisticians, citizens, politicians, etc. come together to offer solutions to improve quality of life in the city. To find such solutions, these people need clear and reliable (qualitative and quantitative) information about specific challenges that residents and visitors face For the variety of stakeholders in the city, many different things might be considered worthy of study, depending on their interests and needs regarding, e.g., employment, financial status, family size, healthcare, mobility, and education. For example, do you know whether your neighborhood issufficiently protected from a fire? What about other neighborhoods in the city? To what extent does a CUNY degree help a person gain employment in the City? In which ways do race or gender or sexual preference play a role in how people experience city life? Can these be quantified in dollar terms? Once you have identified a problem, write an essay that describes a question about city life that you believe is worthy of a statistical study.
