Introduction (Statistics for Economics) Class 11 Economics

Why Economics?

  • Alfred Marshall defines economics as the study of human behavior in everyday life situations, particularly in business activities.
  • A consumer is someone who uses goods and services to fulfill their desires or needs.
  • Consumption refers to utilizing goods and services to satisfy our wants or needs directly.
  • A producer is an individual or entity that creates or sells goods and services with the aim of generating income.

  • Production involves the process of transforming raw materials into useful goods or services.
  • Saving is the portion of income that is not spent on consumption and involves the practice of restraining immediate consumption.
  • Economic activity refers to the production, distribution, and consumption of goods and services. It encompasses all actions that involve the use of resources (such as labour, capital, and land) to produce goods and services that satisfy human wants and needs.
  • The economic problem arises due to the scarcity of resources and the existence of alternative uses for those resources, resulting in the need to make choices.
  • Investment refers to the expenditure made by producers to acquire assets that can generate income.
  • An employee refers to an individual who receives payment in the form of salary or wages from an employer for the work they provide.
  • An employer, in economics, is an individual or organization that hires one or more employees to produce goods or services by offering them compensation in the form of salary or wages.

Consumption, Production and Distribution

  • We're interested in understanding the decision-making process of a consumer, considering their income and numerous purchasing options, in relation to prices. This is referred to as the study of consumption. 
  • We are also interested in understanding the decision-making process of the producer regarding what and how to produce for the market, which is the focus of Production study.  
  • We're interested in understanding the distribution of a country's total income or GDP, through wages, profits, and interest, excluding income from international trade and investment. This is the study of Distribution.

In addition to the three traditional areas of Economics study, modern economics also involves specialized studies on the fundamental issues faced by the country. Disasters impact our lives significantly, hence the need for Statistics in modern economics courses. This subject studies number-based facts systematically, which is crucial in understanding economics. Do you agree with the widely accepted definition of economics now? 

“Economics is the study of how people and society choose to employ scarce resources that could have alternative uses in order to produce various commodities that satisfy their wants and to distribute them for consumption among various persons and groups in society.” 

Difference Between Economic and Non-Economic Activity

Statistics in Economics

  • There is need of special studies addressing a country's fundamental issues, requiring a deeper understanding of economic facts or data. 
  • The aim of gathering this data is to comprehend and dissect these issues, pinpointing their root causes. 
  • For instance, analyzing poverty would involve understanding factors like unemployment, low productivity, and outdated technology. 
  • The analysis of poverty is crucial in developing measures or policies to alleviate it. Without data on the diverse factors that contribute to an economic issue, it is impossible to analyze the problem or create effective policies to address it. 
  • This highlights the fundamental relationship between Economics and Statistics.

What is Statistics

Statistics is the study of collecting, analyzing, interpreting, presenting, and organizing data. In other words, it is a mathematical discipline that aims to collect and summarize data. According to statistician Sir Arthur Lyon Bowley, statistics is defined as "numerical statements of facts in any department of inquiry placed in relation to each other."

  • A Plural Sense Statistics refers to information in terms of numbers or numerical data, such as population statistics, employment statistics etc.
  • A Singular Sense It refers to techniques or methods relating to collection, classification, presentation analysis and interpretation of quantitative data.
