Generally, books on mathematical statistics are restricted to the case of independent identically distributed random variables. In this book however, both this case AND the case of dependent variables, i.e. statistics for discrete and continuous time processes, are studied. This second case is very important for today’s practitioners. Mathematical Statistics and Stochastic Processes is based on decision theory and asymptotic statistics and contains up-to-date information on the relevant topics of theory of probability, estimation, confidence intervals, non-parametric statistics and robustness, second-order processes in discrete and continuous time and diffusion processes, statistics for discrete and continuous time processes, statistical prediction, and complements in probability. This book is aimed at students studying courses on probability with an emphasis on measure theory and for all practitioners who apply and use statistics and probability on a daily basis.

Provides the necessary skills to solve problems in mathematical statistics through theory, concrete examples, and exercises With a clear and detailed approach to the fundamentals of statistical theory, Examples and Problems in Mathematical Statistics uniquely bridges the gap between theory andapplication and presents numerous problem-solving examples that illustrate the relatednotations and proven results. Written by an established authority in probability and mathematical statistics, each chapter begins with a theoretical presentation to introduce both the topic and the important results in an effort to aid in overall comprehension. Examples are then provided, followed by problems, and finally, solutions to some of the earlier problems. In addition, Examples and Problems in Mathematical Statistics features: Over 160 practical and interesting real-world examples from a variety of fields including engineering, mathematics, and statistics to help readers become proficient in theoretical problem solving More than 430 unique exercises with select solutions Key statistical inference topics, such as probability theory, statistical distributions, sufficient statistics, information in samples, testing statistical hypotheses, statistical estimation, confidence and tolerance intervals, large sample theory, and Bayesian analysis Recommended for graduate-level courses in probability and statistical inference, Examples and Problems in Mathematical Statistics is also an ideal reference for applied statisticians and researchers.

The purpose of this book is to present some of the basic concepts and methods of statistics in a clear and understandable manner. The level is appropriate to students with a limited mathematical background. Because statistics allows us to use data to gain insight into a problem, we emphasize understanding rather than mastering statistical technique. This book is organized in 13 chapters under the following topics: Introduction, Frequency distribution and graphs, Data description, Probability and probability distributions, Sampling and sampling distributions, Estimation and hypothesis testing, Simple correlation and regression, Non-parametric statistics, Index numbers, Chi-square test and Introduction to analysis of variance. This text book is intended for undergradute students of various diciplines. However, it can also be used by graduate students and researchers.

Think you can't have fun learning statistics? Think again. "The Manga Guide to Statistics" will teach you everything you need to know about this essential discipline, while entertaining you at the same time. With its unique combination of Japanese-style comics called manga and serious educational content, the EduManga format is already a hit in Japan. In "The Manga Guide to Statistics", our heroine Rui is determined to learn about statistics to impress the dreamy Mr. Igarashi and begs her father for a tutor. Soon she's spending her Saturdays with geeky, bespectacled Mr. Yamamoto, who patiently teaches her all about the fundamentals of statistics: topics like data categorization, averages, graphing, and standard deviation. After all her studying, Rui is confident in her knowledge of statistics, including complex concepts like probability, coefficients of correlation, hypothesis tests, and tests of independence. But is it enough to impress her dream guy? Or maybe there's someone better, right in front of her? Reluctant statistics students of all ages will enjoy learning along with Rui in this charming, easy-to-read guide, which uses real-world examples like teen magazine quizzes, bowling games, test scores, and ramen noodle prices.

An appendix showing how to perform statistics calculations in Microsoft Excel makes it easy to put Rui's lessons into practice. This EduManga book is a translation from a bestselling series in Japan, co-published with Ohmsha, Ltd. of Tokyo, Japan.

To most people the word statistics conjures up images of vast tables of confusing numbers, volumes and volumes of figures pertaining to births, deaths, taxes, populations, and so forth, or figures indicating baseball batting averages or football yardage gained flashing across television screens. This is so because in common usage the word statistics is synonymous with the word data. In a sense this is a reasonably accurate impression because the discipline of statistics deals largely with principles and procedures for collecting, describing, and drawing conclusions from data. Therefore it is appropriate for a text in statistics to start by discussing the nature and scope of statistics. Chapter Two discusses data collection. The purpose of this chapter is to provide the definition of a set of data, define the components of such a data set, present tools that are used to describe a data set, and briefly discuss methods of data collection. Chapter Three presents diagrams, charts and graphs. Chapter Four discusses measure of central tendency. Chapter Five presents measure of dispersion and some practice questions.

Praise for the previous edition of Explaining Psychological Statistics «I teach a master's level, one-semester statistics course, and it is a challenge to find a textbook that is at the right level. Barry Cohen's book is the best one I have found. . . . I like the fact that the chapters have different sections that allow the professor to decide how much depth of coverage to include in his/her course. . . . This is a strong and improved edition of an already good book.» —Karen Caplovitz Barrett, PhD, Professor, and Assistant Department Head of Human Development and Family Studies, Colorado State University «The quality is uniformly good. . . . This is not the first statistics text I have read but it is one of the best.» —Michael Dosch, PhD, MS, CRNA, Associate Professor and Chair, Nurse Anesthesia, University of Detroit Mercy A clear and accessible statistics text— now fully updated and revised Now with a new chapter showing students how to apply the right test in the right way to yield the most accurate and true result, Explaining Psychological Statistics, Fourth Edition offers students an engaging introduction to the field. Presenting the material in a logically flowing, non-intimidating way, this comprehensive text covers both introductory and advanced topics in statistics, from the basic concepts (and limitations) of null hypothesis testing to mixed-design ANOVA and multiple regression. The Fourth Edition covers: Basic statistical procedures Frequency tables, graphs, and distributions Measures of central tendency and variability One- and two-sample hypothesis tests Hypothesis testing Interval estimation and the t distribution
