• 1)

Economic development which aimed at increasing the production of goods and services to meet the needs of a rising population, puts greater pressure on the environment. In the initial stages of development, the demand for environmental resources was less than that of supply. Now the world today is faced with increased demand for environmental resources but their supply is limited, due to overuse and misuse. Sustainable development aims at promoting the kind of development that minimises environmental problems and meets the needs of the present generation without compromising the ability of the future generation to meet their own needs.

The process of globalisation through Iiberalisation and privatisation policies has produced positive and negative results both for India and other countries. It is argued that globalisation should be seen as an 'opportunity' for the developing countries, in terms of becoming important players in the international arena. On the other hand, it is argued that globalisation is a strategy of the developed countries to expand their markets in other countries. It is held that the market driven globalisation has widened the economic disparities among the nations and the people by further compromising the welfare and the identity of the people belonging to the poor countries. Further it has increased the income and quality of consumption of only high-income groups, with the growth concentrating only in select areas in the service sector like IT, telecommunication etc.
Critically analyse the role of globalisation in the development of the Indian economy.

A good indicator of economic growth is a steady increase in the Gross Domestic Product (GDP). GDP is the "market value of all the final goods and services produced in the country during a year". GDP of a country is derived from the different sectors of the economy, namely the agricultural sector, the industrial sector and the service sector. The contribution made by each of these sectors makes up the 'structural composition' of the economy.

The progress of the Indian economy during the first seven plans was impressive. Our industries became more diversified and India became self-sufficient in food production due to the 'Green Revolution'. Land reforms resulted in the abolition of the hated 'Zamindari System'. But in the industrial sector there was dissatisfaction on account of the performance of many public sector interprises. Indian policies were 'inward oriented' and they failed to develop a strong export sector. The need for the reform of economic policy was widely felt in the context of the changing global economic scenario: The New Economic Policy was thereby initiated in 1991 to make India more efficient.

#### Class 11th Economics - Correlation Case Study Questions and Answers 2022 - 2023 - by Study Materials - View & Read

• 1)

'Correlation' studies and measures the direction and intensity of relationship among variables. "Scatter diagram" is a useful technique of visual presentation of the relationship between the two variables, say X and Y. Correlation is commonly classified into negative and positive correlation. Correlation is positive when the variable X rises, variable Y will also rise and vice-versa. This means both X and Y move in the same direction. Correlation is negative when the two variables X and Y move in the opposite directions, i.e., when X rises, Y falls and vice-versa.
The value of co-efficient of correlation (r) lies between minus 1 and plus 1,$-1 \leq r \leq 1$.
(i) If r = 0, the two variables are uncorrelated. There is no linear relation between them.
(ii) If r = $\pm 1$, the correlation is perfect with exact linear relation.
(iii) A high value of r indicates strong linear relationship.
(iv) A low value of r (close to zero) indicates a weak linear relation.
(a) Define a 'Scatter Diagram'.
(i) Does zero correlation mean independence?
(ii) Does r = ±l indicate perfect correlation between the given two variables? (iii) Does a high value of r indicate a weak linear relation?

#### Class 11th Economics - Measures of Dispersion Case Study Questions and Answers 2022 - 2023 - by Study Materials - View & Read

• 1)

Absolute measures of dispersion calculate a value which, at times is difficult to interpret. For example, there are two data sets - Set A and Set B.

 Set A: 500 700 1000 Set B: 1,00,000 1,20,000 1,30,000

We observe that range for Set A is 500 whereas for Set B it is 30,000.
Thus, examples of absolute measure like above may give misleading ideas about the extent of variation. Another weakness of absolute measures of dispersion is that they give the answer in the units in which original values are expressed. As a result if the values are expressed in kilometers the dispersion also will be in kilometers.
To overcome these problems relative measures of dispersion can be used. Each absolute measure has a relative counterpart. For example for range there is a co-efficient of range, which is calculated a $\frac{\mathbf{L}-\mathbf{S}}{\mathbf{L}+\mathbf{S}}$ .
(a) Give the formula for calculating the co-efficient of range.
(b) Highlight the two weaknesses of absolute measures of dispersion.
(c) How can the above problems of absolute measures of dispersion be overcome?

• 1)

The measures of central tendency summarise the data with a single value, which can represent the entire data. It is a single most typical or representative value to describe the entire mass of data. Arithmetic mean is the most commonly used average. It is simple to calculate and is based on all the observations, but it is also unduly affected by the presence of extreme items. Median is a better summary for such data. Mode is generally used to describe the qualitative data. Further Median and Mode can be easily computed graphically.
(a) Define an 'average'.
(b) Elaborate which average is considered to be the mostly commonly used average.
(c) Give one difference between Mean and Mode.

#### Class 11th Economics - Organisation of Data Case Study Questions and Answers 2022 - 2023 - by Study Materials - View & Read

• 1)

The data collected from primary and secondary sources are raw or unclassified. Once the data are collected the next step is to classify them for further statistical analysis. 'Classification' brings order to raw data which can be classified through the frequency distribution in a comprehensive manner. Once you know the techniques of classification, you can easily construct a frequency distribution, both for the continuous and discrete variable. A continuous variable can take any numerical value, e.g., height, weight etc. whereas a discrete variable can take only certain value, e.g., number of children, number of chairs etc.
(a) Explain how does classification of data brings order to raw data.
(b) Give an example each of a discrete variable and a continuous variable.

• 2)

The classification of data as a frequency distribution has an inherent shortcoming. While it summarises raw data making it concise and comprehensible it does not show the datails that are found in raw data. There is loss of information in classifying raw data. Once the data are grouped into classes, an individual observation has no significance in further statistical calculation. This is so because when the data are grouped into classes an individual observation has no significance in further calculation. This is so because when data are grouped as 'classes' all values say in a given class 0-10 are grouped with a frequency of say 6, but not their actual values. All values in this class are assumed to be equal to the middle value of the class interval (i.e., 5).
What do you understand by the 'loss of information' in classified data? Explain with the help of an example.

Thus, the data are primary to the source that collects and processes them for the first time and secondary for all sources that later use such data. Use of secondary data saves time and cost.
