  difference mean in math: Sex Differences in Cognitive Abilities Diane F. Halpern, 2013-03-01 The fourth edition of Sex Differences in Cognitive Abilities critically examines the breadth of research on this complex and controversial topic, with the principal aim of helping the reader to understand where sex differences are found – and where they are not. Since the publication of the third edition, there have been many exciting and illuminating developments in our understanding of cognitive sex differences. Modern neuroscience has transformed our understanding of the mind and behavior in general, but particularly the way we think about cognitive sex differences. But neuroscience is still in its infancy and has often been misused to justify sex role stereotypes. There has also been the publication of many exaggerated and unreplicated claims regarding cognitive sex differences. Consequently, throughout the book there is recognition of the critical importance of good research; an amiable skepticism of the nature and strength of evidence behind any claim of sex difference; an appreciation of the complexity of the questions about cognitive sex differences; and the ability to see multiple sides of an issues, while also realizing that some claims are well-reasoned and supported by data and others are politicized pseudoscience. The author endeavors to present and interpret all the relevant data fairly, and in the process reveals how there are strong data for many different views. The book explores sex differences from many angles and in many settings, including the effect of different abilities and levels of education on sex differences, pre-existing beliefs or stereotypes, culture, and hormones. Sex differences in the brain are explored along with the stern caveat to mind the gap between brain structures and behaviors. Readers should come away with a new understanding of the way nature and nurture work together to make us unique individuals while also creating similarities and differences that are often (but not always) tied to our being female and male. Sex Differences in Cognitive Abilities, Fourth Edition, can be used as a textbook or reference in a range of courses and will inspire the next generation of researchers. Halpern engages readers in the big societal questions that are inherent in the controversial topic of whether, when , and how much males and females differ psychologically. It should be required reading for parents, teachers, and policy makers who want to know about the ways in which males and females are different and similar.
  difference mean in math: Theories of Mathematics Education Bharath Sriraman, Lyn English, 2009-10-13 Advances in Mathematics Education is a new and innovative book series published by Springer that builds on the success and the rich history of ZDM—The Inter- tional Journal on Mathematics Education (formerly known as Zentralblatt für - daktik der Mathematik). One characteristic of ZDM since its inception in 1969 has been the publication of themed issues that aim to bring the state-of-the-art on c- tral sub-domains within mathematics education. The published issues include a rich variety of topics and contributions that continue to be of relevance today. The newly established monograph series aims to integrate, synthesize and extend papers from previously published themed issues of importance today, by orienting these issues towards the future state of the art. The main idea is to move the ?eld forward with a book series that looks to the future by building on the past by carefully choosing viable ideas that can fruitfully mutate and inspire the next generations. Taking ins- ration from Henri Poincaré (1854–1912), who said “To create consists precisely in not making useless combinations and in making those which are useful and which are only a small minority.

  difference mean in math: Introductory Statistics William B. Ware, John M. Ferron, Barbara M. Miller, 2013-02-15 This comprehensive and uniquely organized text is aimed at undergraduate and graduate level statistics courses in education, psychology, and other social sciences. A conceptual approach, built around common issues and problems rather than statistical techniques, allows students to understand the conceptual nature of statistical procedures and to focus more on cases and examples of analysis. Wherever possible, presentations contain explanations of the underlying reasons behind a technique. Importantly, this is one of the first statistics texts in the social sciences using R as the principal statistical package. Key features include the following. Conceptual Focus – The focus throughout is more on conceptual understanding and attainment of statistical literacy and thinking than on learning a set of tools and procedures. Problems and Cases – Chapters and sections open with examples of situations related to the forthcoming issues, and major sections ends with a case study. For example, after the section on describing relationships between variables, there is a worked case that demonstrates the analyses, presents computer output, and leads the student through an interpretation of that output. Continuity of Examples – A master data set containing nearly all of the data used in the book’s examples is introduced at the beginning of the text. This ensures continuity in the examples used across the text. Companion Website – A companion website contains instructions on how to use R, SAS, and SPSS to solve the end-of-chapter exercises and offers additional exercises. Field Tested – The manuscript has been field tested for three years at two leading institutions.

  difference mean in math: Towards Equity in Mathematics Education Helen Forgasz, Ferdinand Rivera, 2012-03-19 ​​This volume gathers together twenty major chapters that tackle a variety of issues associated with equity in mathematics education along the dimensions of gender, culture, curriculum diversity, and matters of a biological nature. The pursuit of equity in mathematics education is an important concern in the history of the present. Since there is no doubt about the significant role of mathematics in almost every aspect of life, it means that all individuals regardless of sex, in any age range, and in whatever context need to be provided with an opportunity to become mathematically able. The publication of this Springer volume on equity in mathematics education is situated at a time when there is strong and sustained research evidence indicating the persistence of an equity gap in mathematics, which has now enabled the mathematics education community to engage in a discourse of access for all. The research studies that are reported and discussed in the volume have been drawn from an international group of distinguished scholars whose impressive, forward-looking, and thought-provoking perspectives on relevant issues incite, broaden, and expand complicated conversations on how we might effectively achieve equity in mathematics education at the local, institutional, and systemic levels. Further, the up-to-date research knowledge in the field that is reflected in this volume provides conceptual and practical outlines for mechanisms of change, including models, examples, and usable theories that can inform the development of powerful equitable practices and the mobilization of meaningful equity interventions in different contexts of mathematics education.​

  difference mean in math: The Mathematics of Sex Stephen J. Ceci, Wendy M. Williams, 2009-09-02 Nearly half of all physicians and biologists are females, as are the majority of new psychologists, veterinarians, and dentists, suggesting that women have achieved equality with men in the workforce. But the ranks of professionals in math-intensive careers remain lopsidedly male; up to 93% of tenure-track academic positions in some of the most mathematically-oriented fields are held by men. Three main explanations have been advanced to explain the dearth of women in math-intensive careers, and in The Mathematics of Sex, Stephen J. Ceci and Wendy M. Williams describe and dissect the evidence for each. The first explanation involves innate ability--male brains are physiologically optimized to perform advanced mathematical and spatial operations; the second is that social and cultural biases inhibit females' training and success in mathematical fields; the third alleges that women are less interested in math-intensive careers than are men, preferring people-oriented pursuits. Drawing on research in endocrinology, economics, sociology, education, genetics, and psychology to arrive at their own unique, evidence-based conclusion, the authors argue that the problem is due to certain choices that women (but not men) are compelled to make in our society; that women tend not to favor math-intensive careers for certain reasons, and that sex differences in math and spatial ability cannot adequately explain the scarcity of women in these fields. The Mathematics of Sex represents the first time such a thorough synthesis of data has been carried out to solve the puzzle of women's underrepresentation in math-intensive careers. The result is a readable, engaging account suitable not only for academics in an array of disciplines, but for general readers as well--including educators, science policymakers, parents of daughters, and anyone intellectually curious about a key controversy of our time.

  difference mean in math: Sampling Sharon L. Lohr, 2021-11-30 The level is appropriate for an upper-level undergraduate or graduate-level statistics major. Sampling: Design and Analysis (SDA) will also benefit a non-statistics major with a desire to understand the concepts of sampling from a finite population. A student with patience to delve into the rigor of survey statistics will gain even more from the content that SDA offers. The updates to SDA have potential to enrich traditional survey sampling classes at both the undergraduate and graduate levels. The new discussions of low response rates, non-probability surveys, and internet as a data collection mode hold particular value, as these statistical issues have become increasingly important in survey practice in recent years... I would eagerly adopt the new edition of SDA as the required textbook. (Emily Berg, Iowa State University) What is the unemployment rate? What is the total area of land planted with soybeans? How many persons have antibodies to the virus causing COVID-19? Sampling: Design and Analysis, Third Edition shows you how to design and analyze surveys to answer these and other questions. This authoritative text, used as a standard reference by numerous survey organizations, teaches the principles of sampling with examples from social sciences, public opinion research, public health, business, agriculture, and ecology. Readers should be familiar with concepts from an introductory statistics class including probability and linear regression; optional sections contain statistical theory for readers familiar with mathematical statistics. The third edition, thoroughly revised to incorporate recent research and applications, includes a new chapter on nonprobability samples—when to use them and how to evaluate their quality. More than 200 new examples and exercises have been added to the already extensive sets in the second edition. SDA’s companion website contains data sets, computer code, and links to two free downloadable supplementary books (also available in paperback) that provide step-by-step guides—with code, annotated output, and helpful tips—for working through the SDA examples. Instructors can use either R or SAS® software. SAS® Software Companion for Sampling: Design and Analysis, Third Edition by Sharon L.

  difference mean in math: Mathematical and Statistics Anxiety: Educational, Social, Developmental and Cognitive Perspectives Kinga Morsanyi, Irene Cristina Mammarella, Denes Szűcs, Carlo Tomasetto, Caterina Primi, Erin Anne Maloney, 2017-01-19 Mathematical anxiety is a feeling of tension, apprehension or fear which arises when a person is faced with mathematical content. The negative consequences of mathematical anxiety are well-documented. Students with high levels of mathematical anxiety might underperform in important test situations, they tend to hold negative attitudes towards mathematics, and they are likely to opt out of elective mathematics courses, which also affects their career opportunities. Although at the university level many students do not continue to study mathematics, social science students are confronted with the fact that their disciplines involve learning about statistics - another potential source of anxiety for students who are uncomfortable with dealing with numerical content. Research on mathematical anxiety is a truly interdisciplinary field with contributions from educational, developmental, cognitive, social and neuroscience researchers. The current collection of papers demonstrates the diversity of the field, offering both new empirical contributions and reviews of existing studies. The contributors also outline future directions for this line of research.

  difference mean in math: Macro Cultural Psychology Carl Ratner, 2011-08-01 This book articulates a bold, new, systematic theory of psychology, culture, and their interrelation. It explains how macro cultural factors -- social institutions, cultural artifacts, and cultural concepts -- are the cornerstones of society and how they form the origins and characteristics of psychological phenomena. This theory is used to explain the diversity of psychological phenomena such as emotions, self, intelligence, sexuality, memory, reasoning, perception, developmental processes, and mental illness. Ratner draws upon Lev Vygotsky's sociocultural psychology, Bronfenbrenner's ecological psychology, as well as work in sociology, anthropology, history, and geography, to explore the political implications and assumptions of psychological theories regarding social policy and reform. The theory outlined here addresses current theoretical and political issues such as agency, realism, objectivity, subjectivism, structuralism, postmodernism, and multiculturalism.
