The 12th edition of the "**STATISTICS**" textbook for class 11 has been collaboratively authored by three subject specialists, guaranteeing high-quality content for the **book**. The subject of statistics revolves around the process of gathering and organizing data, analyzing it, and employing various methods for its presentation.

**collecting**and

**organizing data**, summarizing and analyzing numerical information, and interpreting the results. It also involves the application of probability theory and mathematical techniques to practical scenarios.

## What does the book contain?

This **Punjab Text Book** consists of nine chapters, divided into two sections. The first section focuses on **statistics**, while the second section delves into **probability**. Chapters 1 to 4 provide an introduction to the subject of statistics, covering essential terms and concepts. In Chapter 5, the book explores the topic of **index numbers** and their application in analyzing price trends.

**dedicated to probability**. Chapter 6 serves as an

**introduction to probability**, establishing foundational knowledge by discussing concepts such as sets. The core concepts and principles of probability are then covered in Chapters 7, 8, and 9, which form the central portion of the probability section.

## Chapter No. 1 : Introduction To Statistics

The opening chapter serves as an introduction to the field of **statistics**, providing a concise overview of its **historical development**, **definition**, and **key terms**. It aims to familiarize students with fundamental statistical concepts. The chapter also highlights the significance of statistics across different disciplines by showcasing its applications. Furthermore, it explores the **concept of variables**, their types, and the distinction between descriptive and inferential statistics. By examining the main components of a **statistical problem**, the chapter provides a comprehensive understanding. Additionally, it addresses the two primary sources from which data can be obtained.

## Chapter No. 2 : Representation Of Data

The chapter provides detailed explanations of the simple tabular and graphical techniques employed to present data in a**comprehensible manner**. It delves into the tabular representation of discrete data using cumulative frequency distribution. Furthermore, the chapter explores various graphical representations of data, including bar diagrams,

**multiple bar**

**diagrams**,

**histograms**,

**frequency polygons**,

**frequency curves**, and

**scatter plots**. These graphical methods facilitate a visual understanding of the data and aid in its interpretation.

## Chapter No. 3 : Measure Of Location

The chapter encompasses an extensive discussion of**statistical distributions**, covering their concepts,

**properties**,

**calculations**,

**advantages**,

**disadvantages**, and

**interrelationships**. It offers a quantitative analysis of the distributions, highlighting the central tendency and the relative positioning of observations within the

**distribution.**This comprehensive exploration provides a deeper understanding of the characteristics and implications of

**various statistical distributions**.

## Chapter No. 4 : Measure of Dispersion

The chapter focuses on the dispersion of information within a dataset, also known as data variation. It introduces the concept of variability and its different types, including**absolute measures**and

**relative measures**. The chapter provides a detailed explanation of

**absolute measures**of variability, such as

**Range**,

**Quartile Deviation**,

**Mean Deviation**,

**Variance**, and

**Standard Deviation**. Additionally, it delves into the discussion of the Coefficient of Variation as the

**primary relative measure**, while mentioning other relative measures and their respective formulas. Furthermore, the chapter explores measures related to the shape of the distribution, which are dependent on moments, and elaborates on skewness and kurtosis.

## Chapter No. 5 : Index Numbers

What sets this chapter apart from others is its specific focus on**price-related data**. It delves into the concept of

**Index numbers**, which are utilized to gauge the relative changes in variables over time. The chapter provides a comprehensive overview of the

**significance**,

**definition**,

**construction**,

**calculation**,

**types**, and

**limitations of index numbers**. It also explains different types of indices and their respective calculation methods. Towards the end of the chapter, it discusses the meaning and construction of three price indices

**(CPI, SPI, WPI)**calculated by the

**Federal Bureau of Statistics in Pakistan**, adding an engaging element to the content.

## Chapter No. 6 : Probability

From this point forward, the**book**delves into the intriguing aspects of the subject. The chapter initiates by providing a concise overview of set theory and then introduces the concept of probability. It systematically develops methods to address problems related to chance events throughout the chapter. The discussion commences with an explanation of

**sets**, their different

**types**, and

**operations**that can be performed on sets.

## Chapter No. 7 : Random Variables

The subsequent chapter marks the exploration of deeper and captivating concepts in probability as it unveils the concept of**random variables**. It presents a definition of

**random numbers**and briefly touches upon their

**generation**and

**applications**. Furthermore, the chapter elucidates the concept of random variables through illustrative examples, culminating with a concise explanation of discrete and continuous

**random variables**.

## Chapter No. 8 : Probability Distributions

Continuing from the previous chapter's exploration of discrete and continuous**random variable**s, this chapter delves deeper into the topic. It begins by defining probability distributions for these two types of random variables: probability mass function for discrete random variables and probability density function for continuous

**random variables**. The chapter covers the properties and applications of univariate discrete and continuous distributions. Furthermore, it presents graphical representations of probability distributions using

**histograms**and bar charts. The terms Expectation, Variance, and Distribution function are thoroughly explained with the aid of multiple examples.

## Chapter No. 9 : Binomial & Hypergeometric Probability Distribution

This chapter focuses on scenarios involving only two possible outcomes, which are categorized as success or failure. The primary subjects covered in this chapter are the**Binomial**probability distribution and the

**Hypergeometric**Distribution, along with their respective

**mean**and

**variance**. The chapter delves into the concepts and properties of these distributions, providing a comprehensive understanding of their applications.
