Question - 5 : -
Mark the following statements as true or false.

(i) Statistics can only deal with quantitative data.

(ii) Statistics solves economic problems.

(iii) Statistics is of no use to Economics without data.

Answer - 5 : -

(i) Statistics can only deal with quantitative data. False

Statistics deals with both quantitative data as well as with qualitative data. Statistics not only reveals quantitative information but also reflects the qualitative aspect of data like better, worse off, highly skilled, etc. Although, the qualitative aspects can neither be easily measured nor can be expressed in quantitative terms, but statistics describes the attributes of these variables.

(ii) Statistics solves economic problem. True

Statistics acts as a tool in the hands of economists that enables them to understand and evaluate an economic problem. The causes of a problem are identified through statistical tools and methods and policies and rectification measures are formulated accordingly.

(iii) Statistics is of no use to economics without data. True

Data enable economists to present economic facts in a precise and concise form. Data itself is self explanatory. For example, if the per capita monthly income in India has increased from Rs 300 to Rs 600 during 1974 to 1984, then just by looking at the figures an economist would not only understand the quantitative increase in the per capita income but also can assess the implicit qualitative aspects associated with this increase like higher standard of living, low level of poverty, higher level of savings, etc.

Question - 6 : -
˜The Government and policy makers use statistical data to formulate suitable policies of economic developmentâ. Illustrate with two examples.

Answer - 6 : -

The statistical data is of prime importance for the government and the policy makers. The statistical data not only help them to analyse and evaluate the outcomes of the past policies but also assist them to take corrective measures and to formulate new policies accordingly. Further, the statistical data also help the government to ascertain various needs and priorities for the pursuit of the common goal of economic development. For example, if Indian Government aims at encouraging the production level, then it formulates its economic policy based on the average production level of the past three years. Another example could be the preparation of government budget. The previous data of government expenditures and government revenues are taken into consideration for estimating the allocation of funds among various projects.

Question - 7 : -
.“You have unlimited wants and limited resources to satisfy them.” Explain by giving two examples.

Answer - 7 : -

Every economy faces the problem of scarcity. ‘Scarcity of resources’ implies that there are unlimited wants to be fulfilled by limited resources. The basic concern of an economy is to allocate the scarce resources to the best possible use in the face of unlimited wants. Thus, the problem of scarcity forces an economy to make a choice among various alternatives. For example, an economy endowed with a given level of resources has to make a choice between the production of guns and breads. The choice of the economy (i.e. either to produce guns or bread and in what quantities) depends on the need and goal of the economy. While the production of bread will make the economy devoid of the security level, whereas, the production of guns will not provide sufficient food for the population. The same problem of scarcity can be felt at an individual level. For example, with a given amount of money say, Rs 20,000, one cannot buy a TV and a sofa set simultaneously. Thus, the individual needs to make a choice between the alternatives according to his/her priority.

Question - 8 : -
Statistical methods are no substitute for common sense. Comment..

Answer - 8 : -

A statement of attention to the students of statistics is being referred here. Statistical data should not be believed blindly as it can be misinterpreted or misused. The statistical data may be politically influenced, may involve personal biasness or may undergone data mining (manipulations). Moreover, statistical data and methods fail to reveal the errors committed by an investigator while surveying and collecting data. Thus, the students are advised to use their common sense while working with the statistical data. This point can be better understood with the help of the following example. According to a survey that was conducted on the Death Rate, it was found that the number of deaths per 1,000 people was more in doctors accessible regions compared to the death rate in the remote areas. Such statistical data violate common sense and thereby is misleading. Therefore, the students are advised not to have lope sided beliefs on the statistical data and methods but simultaneously should evaluate the statistical results logically and should offend the results if it violates their common sense.

Thus, it can be concluded that statistics is like clay that can be transformed in either good or bad way in order to draw right or wrong conclusions. Hence, the numerical data should not be deliberately used without applying common sense.

Question - 9 : -
.How will you choose the wants to be satisfied?

Answer - 9 : -

An individual fulfills his/her wants according to his/her needs, satisfactions and priority attached to different wants. Those wants will be fulfilled first that provides the highest satisfaction to the individual and to which the individual has attached the top most priority. Further, the choice of want also depends on the need of the hour and availability of the goods and also on the availability of means (money) to realise a particular want. Thus, depending on all these conditions, we can say that an individual having sufficient budget will fulfill a particular need that would fetch him/her the highest possible satisfaction.

Question - 10 : -
.What are your reasons for studying Economics?

Answer - 10 : -

The need to study economics stems from the basic problem of scarcity and choice. The basic concern of economics is to allocate the scarce resources to the best possible use in the face of unlimited wants. Consequent to the scarce availability of resources, an economy needs to make choice to allocate the scarce resources to the areas with maximum possible and optimum returns.Thus, the study of economics is very important. The following are the reasons that make the study of economics inevitable.

1. To study the Theory of Consumption

The Theory of Consumption deals with the study of the behaviour of the consumers in different types of market. The basic concern of this theory is how a rational consumer makes his/her preferences to get the maximum possible satisfaction in the facet of fixed level of income, given prices of the goods, etc.

2. To study the Theory of Production

The Theory of Production studies the production decisions of the producers in different types of market. The theory investigates how a producer takes production decisions. The theory highlights how a producer combines different inputs (given their prices) in order to minimise the cost of production and to maximise the profits.

3. To study the Theory of Distribution

The study of economics makes us aware about the distribution of national income. In other words, how the income arising from the total production of an economy is distributed in the form of wage, profit, rent and interest to different factor owners (like, labour, entrepreneur, land, capital).

4. To study the basic macroeconomic problems faced by an economy

Economics proves as the most powerful tool to understand and analyse the root cause of basic macroeconomic problems faced by an economy like, poverty, unemployment, income disparity, etc. Economics helps us not only in understanding the interrelationship among these problems (like the relationship between poverty and unemployment) but also to take various corrective measures.
