Chapter 1: Introduction
The first chapter of the NCERT book Statistics for Economics Class 11 introduces important points about economics. It leads to defining statistics, encompassing its scope according to Bowley’s view, highlighting the important characteristics of statistics in a plural sense. It also investigates the concept in its singular form, as explained by Seligman, enabling students to comprehend the role and significance of statistics in economics. The chapter closes with the fallibility of statistics. Additionally, exercises at the chapter end contain questions that the students can use to measure their comprehension of the content dealt with.
Chapter 2: Data Collection
Chapter 2 of the NCERT textbook for Class 11 Economics Statistics explores the sources and types of data, distinguishing between primary and secondary data. The chapter explains in detail the different statistical techniques used for collecting data, including:
- Direct personal investigation
- Indirect oral investigation
- Collection of information from correspondents or local sources
- Use of schedules and questionnaires
- Censuses
- Sampling techniques
Chapter 3: Data Organization
Chapter 3 of NCERT Statistics for Class 11 introduces students to the important topic of data organization under the classification heading. After introducing the chapter’s subject matter, the chapter discusses the objectives and fundamental features of good classification, laying a basic concept on how statistical data must be dealt with.
The chapter then acquaints students with various statistical series essential for efficiently structuring data. These are:
- Individual series: This category is concerned with data points viewed separately.
- Frequency series: These series categorize data points that have a common frequency.
Much of the chapter is devoted to discussing frequency distributions, one of the important statistics tools used to analyze data sets’ details. The chapter aims to acquire the student with an intensive knowledge about organizing data to create a better understanding and facilitate easy analysis.
Further, the chapter comprises in-depth practice problems with exam questions of similar kinds. Solving these exercises repeatedly helps students deal with different questions that may come their way in the examination to become ready and surefooted about statistics.
Chapter 4: Presentation of Data
Chapter 4 of the NCERT Class 11 Economics Statistics deals with different modes of presenting data, an important topic in statistical analysis. The chapter familiarizes students with three main modes of presenting data:
- Textual Presentation: In which data is presented in the text.
- Tabular Presentation: In which data is presented in tables.
- Diagrammatic Presentation: In which data is depicted through different graphical forms.
Students not only acquire the practical techniques required to represent data graphically but also the theoretical underpinnings that govern these graphic displays. The chapter finishes by considering the strengths and weaknesses of graphical data presentation, with a fair assessment of this vital statistical tool.
Chapter 5: Measures of Central Tendency
Measurements of central tendency are concerned with the central value of a series of statistics. This chapter mostly discusses the various aspects of statistics measurements. Through this chapter of the NCERT books on Class 11 Economics Statistics, economics students can learn how to find the arithmetic mean step by step. By following this book, students can easily learn the tricks and techniques for finding various statistical data. For instance, Median, Percentile, Quartiles, and Mode applications often become intricate and troublesome.
However, NCERT books have made all these concepts easy to understand so that students can understand them without losing much time. Also, by doing the exercise at the end, you can clear your concept immediately.
Chapter 6: Measures of Dispersion
Chapter 6 of the NCERT textbooks of Class 11 Economics Statistics focuses on the measure of dispersion, a significant statistical tool that indicates the spread or variation of a data set. The chapter comprehensively analyzes all the methods for measuring dispersion to give students a thorough knowledge of every method. Some of the measures of dispersion are covered as key concepts:
- Range: The variation between the maximum and minimum values in the data set.
- Mean Deviation: The mean of the absolute deviations from a central point, such as the mean or median.
- Quartile Deviation: Indicates the spread of the middle 50% of data points.
- Standard Deviation: The most widely used measure that expresses the degree of variation or dispersion of a collection of values.
The in-depth explanations in this chapter demystify these concepts, which are sometimes abstract and hard for students to understand. Such calculations may look complicated and formidable, and because of this, interest in such important concepts dwindles.
Nonetheless, by employing the simple explanations and step-by-step procedures described in the NCERT textbook, students can understand how to properly implement these measures of dispersion comprehensively. The book leads students through the interpretation and day-to-day application of these procedures. This allows them to obtain the best results and stay interested in the subject. The basic understanding is instrumental in gaining awareness of variability in data, an important skill in statistics.
Chapter 7: Correlation
Chapter 7 of the NCERT books for Class 11 Economics Statistics delves into the concept of correlation, a statistical technique used to determine the relationship between variables, such as demand and price. This chapter categorizes correlation into two main types:
- Positive Correlation: An increase in one variable leads to an increase in the other.
- Negative Correlation: Where an increase in one variable leads to a decrease in the other.
Students will also explore the degree of correlation, understanding how strongly two variables are related. The chapter provides an in-depth discussion of various methods used to estimate correlation, including Karl Pearson’s coefficient of correlation, which is a key component of this chapter.
Chapter 8: Index Numbers
Chapter 8 of NCERT books for Class 11 Economics Statistics deals with index numbers. This important statistical tool is necessary for students, particularly those appearing for board exams or national entrance tests. Understanding this topic is the key to solving examination questions about this subject.
