CBSE Class 11 Statistics: Chapter 1 - Introduction NCERT Solutions

(i) False. Statistics is a discipline that can deal with both quantitative data (numerical information) and qualitative data (descriptive information). For instance, statements about attributes of a group, like literacy rates or poverty levels, are qualitative in nature but are crucial statistical information used in economics.

(ii) True. Statistics provides essential tools and data that economists use to understand, analyze, and find solutions to various economic problems. By examining quantitative and qualitative facts, economists can identify causes and effects, aiding in policy formulation.

(iii) True. Data is the foundation upon which statistics operates. Without data, economic facts remain vague and unconvincing. Statistical methods applied to data help in presenting economic information precisely, making it more understandable and actionable for economic analysis and policy-making.

Activities commonly observed at a bus stand or a market place include:

• Buying and selling of goods (e.g., fruits, clothes, groceries).
• Providing services (e.g., a rickshaw puller transporting passengers, a vendor selling food, a shopkeeper assisting customers).
• Transportation services (e.g., buses, taxis).
• Manufacturing or production (e.g., a small workshop making items).
• Consumption (people buying and using goods and services).

All these activities are considered economic activities because they involve the use of scarce resources (like labor, capital, land) to produce, distribute, or consume goods and services, and are generally undertaken with the objective of earning money or achieving monetary gain.

Statistical data is vital for governments and policymakers to understand the current economic situation, predict future trends, and design effective policies. Here are two examples:

1. Budget Preparation: The Ministry of Finance relies heavily on statistical data regarding the nation's revenue (taxes collected, other income sources) and expenditure (spending on infrastructure, defense, social welfare, etc.). This data allows them to prepare the annual budget, allocate funds appropriately, and plan for fiscal management. For instance, data on tax collection efficiency helps in setting revenue targets, while data on public spending needs guides resource allocation.
2. Planning for Economic Growth: To promote economic development, planners need to understand the relationship between investments and national income, or the impact of certain policies on employment. For example, if statistical data shows a low correlation between current investment and future national income growth, planners might adjust investment strategies or focus on sectors with higher multiplier effects. Similarly, data on unemployment rates can guide policies aimed at job creation.

Other examples include banking organizations using statistical data to fix interest rates and formulate credit policies, or health ministries using data on disease prevalence to plan public health initiatives.

This statement highlights the fundamental economic problem of scarcity. It means that human desires for goods and services are virtually endless, while the resources (like land, labor, capital, time) available to produce these goods and services are limited. This disparity forces individuals, households, and entire economies to make choices about how to allocate their scarce resources to satisfy their most pressing wants.

Here are two examples:

1. Individual Choice: Suppose an individual has a monthly income of ₹20,000. Their wants might include buying a new smartphone, going on a vacation, paying rent, buying clothes, and saving for the future. However, the ₹20,000 income is a limited resource. The individual must prioritize and choose which wants to satisfy first, perhaps deciding to buy the smartphone and postpone the vacation due to budget constraints.
2. Societal Choice: A government has a limited budget (limited resources) to address various societal needs (unlimited wants). It must decide whether to allocate more funds to healthcare, education, infrastructure development, or defense. For instance, if the government decides to increase spending on building new roads (infrastructure), it might have to reduce its budget for public health programs, thereby making a choice based on perceived priorities.

In essence, the problem of choice arises because we cannot have everything we want due to resource limitations.
