About the Book

In today’s data-driven world, the need for a solid understanding of statistics has become increasingly important. This textbook aims to provide you with a comprehensive and practical introduction to the field of applied statistics. Whether you are an applied statistician or a student looking to gain expertise in data analysis, this book will equip you with the necessary tools and knowledge to navigate the complexities of statistical analysis. The syllabus of this textbook covers a wide range of topics that are essential for understanding and applying statistical methods.
We will delve into the design of sample surveys. We will explore concepts such as population, sample, sampling unit, parameter, statistic, sampling error, and sampling distribution. We will also discuss the steps involved in conducting sample surveys and examine the sources and treatment of non-sampling errors. Furthermore, we will explore the advantages and limitations of sampling, along with the various types of sampling methods. This textbook is designed to be accessible to non-statisticians, while still providing a thorough understanding of statistical concepts and techniques. It follows a practical approach, focusing on using computer software for data analysis rather than delving deeply into mathematical theory. The ANOVA is a two-way classification method that uses only one observation per cell. Mathematical analysis, the significance and uses of experiment design, experimental principles such as CRD, RBD, LSD.
Finding the trend using the moving average method and determining the seasonal indices by their relative to moving mean using least squares (linear, parabolic, and logistic regression) Comparative methods’ tendency to tend and relationship. Index numbers, their properties, and the limitations of samples and weighed index numbers. Laspeyre’s, Paasche’s and Fishers index numbers. Criteria of a good index number, problems involved in the construction of index number, Fisher’s ideal index. Index numbers are based on fixed and chain values, while the cost of living and wholesale price index number are also subject to base shifting, splicing, and deflation.
Vital statistics: Detailed information on the essential statistics sources for the registration method and census method, as well as their usage including the crude death rate, age-specific death rate, standardized death ratio, crude birth rate (where applicable), fertility rate overall, total fertility rates, and population growth. The natural increase in pearls, their raw rate, vital index and other indicators of reproduction, the construction and use of life tables as well as abbreviated tables of existence.
