| what is 90 confidence interval: Confidence Intervals for Discrete Data in Clinical Research Vivek Pradhan, Ashis Gangopadhyay, Sandeep M. Menon, Cynthia Basu, Tathagata Banerjee, 2021-11-14 Confidence Intervals for Discrete Data in Clinical Research is designed as a toolbox for biomedical researchers. Analysis of discrete data is one of the most used yet vexing areas in clinical research. The array of methodologies available in the literature to address the inferential questions for binomial and multinomial data can be a double-edged sword. On the one hand, these methods open a rich avenue of exploration of data; on the other, the wide-ranging and competing methodologies potentially lead to conflicting inferences, adding to researchers' confusion and frustration and also leading to reporting bias. This book addresses the problems that many practitioners experience in choosing and implementing fit for purpose data analysis methods to answer critical inferential questions for binomial and count data. The book is an outgrowth of the authors' collective experience in biomedical research and provides an excellent overview of inferential questions of interest for binomial proportions and rates based on count data, and reviews various solutions to these problems available in the literature. Each chapter discusses the strengths and weaknesses of the methods and suggests practical recommendations. The book's primary focus is on applications in clinical research, and the goal is to provide direct benefit to the users involved in the biomedical field. |

| what is 90 confidence interval: The Practice of Statistics AP Daniel S. Yates, David Moore, George P. McCabe, 1999 When The College Board created the Advanced Placement (AP) statistics course several years ago, they recommended several college books that closely match their syllabus. The top two books on this short list were Moore and McCabe's Introduction to the Practice of Statistics and Moore's The Basic Practice of Statistics. Still, these book lacked several key elements such as activities and special topics. So, starting with the classic features of IPS and BPS, veteran AP statistics instructor Dan Yates has fashioned a text that perfectly matches the College Board’s recommended syllabus. The result is the #1 book in the AP statistics market: The Practice of Statistics, TI-83 Graphing Calculator Enhanced. Because this book was written for bright high school students who are at an advanced reading level, it has also sold to many colleges and universities. These institutions love the idea of a David Moore book integrating the TI-83 Graphing Calculator, which is the most popular statistics calculator in the market. For colleges and universities who require or recommend that their students use the TI-83 Graphing Calculator, TPS is the appropriate text. |

| what is 90 confidence interval: Soil Conservation Service Curve Number (SCS-CN) Methodology S.K. Mishra, V.P. Singh, 2013-03-14 The Soil Conservation Service (SCS) curve number (CN) method is one of the most popular methods for computing the runoff volume from a rainstorm. It is popular because it is simple, easy to understand and apply, and stable, and accounts for most of the runoff producing watershed characteristics, such as soil type, land use, hydrologic condition, and antecedent moisture condition. The SCS-CN method was originally developed for its use on small agricultural watersheds and has since been extended and applied to rural, forest and urban watersheds. Since the inception of the method, it has been applied to a wide range of environments. In recent years, the method has received much attention in the hydrologic literature. The SCS-CN method was first published in 1956 in Section-4 of the National Engineering Handbook of Soil Conservation Service (now called the Natural Resources Conservation Service), U. S. Department of Agriculture. The publication has since been revised several times. However, the contents of the methodology have been nonetheless more or less the same. Being an agency methodology, the method has not passed through the process of a peer review and is, in general, accepted in the form it exists. Despite several limitations of the method and even questionable credibility at times, it has been in continuous use for the simple reason that it works fairly well at the field level. |
