Book Description
Análise de Dados de uma Avaliação Nacional de Desempenho Educacional é o quarto de cinco volumes da série Avaliações Nacionais de Desempenho Educacional. Os outros volumes descreveram os procedimentos em uma avaliação até ao ponto em que os dados foram preparados para a análise estatística, o tópico deste volume. As análises concretas a ser realizadas dependerão das necessidades de informação dos formuladores de políticas e dos gestores no âmbito do ensino. Na maioria das avaliações nacionais, relacionam-se com a qualidade da aprendizagem dos alunos, fatores relacionados com a aprendizagem, questões de equidade, e, em alguns casos, alterações nos resultados educacionais ao longo do tempo. O Volume 4, que compreende duas partes, fornece instruções pormenorizadas acerca de como analisar dados coligidos em uma avaliação nacional. A Parte I prevê uma introdução geral à s análises estatísticas normalmente realizadas nas avaliações em grande escala, avaliando a tendência central e a dispersão das pontuações dos alunos e as relações entre as variáveis. A Parte II descreve o software IATA (Análise de Item e de Teste), que utiliza a teoria clássica dos testes e a teoria de resposta ao item para estabelecer escalas onde reportar as pontuações dos alunos. Os passos da análise das administrações de testes piloto e finais estão descritos detalhadamente. É acompanhado por um CD que contém exercícios especialmente concebidos e arquivos de dados de suporte para ambas as partes do volume. Este livro será de interesse para os especialistas em avaliação de governos nacionais, regionais e locais; instituições de investigação; e universidades.

Book Description
Cognitive mathematics provides insights into how mathematics works inside the brain and how it is interconnected with other faculties through so-called blending and other associative processes. This handbook is the first large collection of various aspects of cognitive mathematics to be amassed into a single title, covering decades of connection between mathematics and other figurative processes as they manifest themselves in language, art, and even algorithms. It will be of use to anyone working in math cognition and education, with each section of the handbook edited by an international leader in that field.

Book Description
Data Science for Business and Decision Making covers both statistics and operations research while most competing textbooks focus on one or the other. As a result, the book more clearly defines the principles of business analytics for those who want to apply quantitative methods in their work. Its emphasis reflects the importance of regression, optimization and simulation for practitioners of business analytics. Each chapter uses a didactic format that is followed by exercises and answers. Freely-accessible datasets enable students and professionals to work with Excel, Stata Statistical Software®, and IBM SPSS Statistics Software®. - Combines statistics and operations research modeling to teach the principles of business analytics - Written for students who want to apply statistics, optimization and multivariate modeling to gain competitive advantages in business - Shows how powerful software packages, such as SPSS and Stata, can create graphical and numerical outputs

Book Description
Creating landscapes of investigation is a primary concern of critical mathematics education. It enables us to organise educational processes so that students and teachers are able to get involved in explorations guided by dialogical interactions. It attempts to address explicit or implicit forms of social injustice by means of mathematics, and also to promote a critical conception of mathematics, challenging the assumption that the subject represents objectivity and neutrality. Landscapes of Investigation provides many illustrations of how this can be done in primary, secondary, and university education. It also illustrates how exploring landscapes of investigation can contribute to mathematics teacher education programmes. This edited volume is the result of a collaboration established through the Colloquium in Research in Critical Mathematics Education, which took place in 2016, 2018, and 2019 in Brazil. Its twenty-eight contributors are young researchers from Brazil, Chile, Colombia, India, Mexico and the USA, who are dedicated to the further development of critical mathematics education. Organised in eighteen chapters, the volume presents examples of engaging students from a diversity of social and economic backgrounds, age ranges, and abilities across different countries. The chapters present original findings on the social aspects of all levels of mathematics education. Landscapes of Investigation is of particular relevance to those with an interest in the potential of mathematics education to challenge social injustices.

Book Description
An Introduction to Statistical Learning provides an accessible overview of the field of statistical learning, an essential toolset for making sense of the vast and complex data sets that have emerged in fields ranging from biology to finance, marketing, and astrophysics in the past twenty years. This book presents some of the most important modeling and prediction techniques, along with relevant applications. Topics include linear regression, classification, resampling methods, shrinkage approaches, tree-based methods, support vector machines, clustering, deep learning, survival analysis, multiple testing, and more. Color graphics and real-world examples are used to illustrate the methods presented. This book is targeted at statisticians and non-statisticians alike, who wish to use cutting-edge statistical learning techniques to analyze their data. Four of the authors co-wrote An Introduction to Statistical Learning, With Applications in R (ISLR), which has become a mainstay of undergraduate and graduate classrooms worldwide, as well as an important reference book for data scientists. One of the keys to its success was that each chapter contains a tutorial on implementing the analyses and methods presented in the R scientific computing environment. However, in recent years Python has become a popular language for data science, and there has been increasing demand for a Python-based alternative to ISLR. Hence, this book (ISLP) covers the same materials as ISLR but with labs implemented in Python. These labs will be useful both for Python novices, as well as experienced users.

Book Description
This is the first e-book that presents some insights into the construction of Mokken scales with complex survey data, and, in particular, the estimation of Mokken's scalability coefficients - Hij, Hi, and H - with binary responses. Every day, researchers work with complex samples selected from finite populations of interest to make inferences about population parameters. However, in many situations these samples are assumed as SRS samples. Serious consequences have been reported in the complex survey data literature; when this assumption is considered. I invite you to find out a little more about some relevant contributions to the development of the Psychometry under complex sampling designs, as highlighted in this e-book. Keywords: Mokken scaling, Mokken scale analysis, complex data, Complex Mokken, design effect, clustering, sampling weights, stratification, clustered samples, variance estimation, point estimation, large-scale educational surveys, Jackknife resampling technique, Non Parametric Item Response Theory.
