10. “Sampling is the best method of collecting primary data” – Justify this statement.                  4
Ans: A Sample is that part of the universe which we select for the purpose of investigation. Sampling is the process of learning about the population on the basis of sample drawn from it. In sampling technique only a part of the universe is studied instead of every unit of the universe.
Sampling is best method of collecting primary data due to the following reasons:
1. Very accurate as compared to other method.
2. Economical in nature because it involves less cost as compared to other methods.
3. Very reliable as compared to other methods.
4. It involves less time as compared to other.

Explain the significance of an index number.                     4
Ans: Index number is an indicator of changes in prices and quantities. It is a specialized average designed to measure the change in a group of related variables over a period of time. These index numbers are also known as barometers of economic activity. It offers a device of estimating the relative changes of a variable when measurement of actual changes is not possible.  It is also an indicator of inflationary or deflationary tendencies. Advantages of index number:
1. Measurement of change in the price level or the value of money.
2. Index number helps to ascertain the living standards of people.
3. Price index numbers serve as a useful guide to the business community in planning.
4. Index of exports and imports provides useful information regarding foreign trade.
13. Define Standard deviation, Range, Quartile deviation, Lorenz curve, Mean deviation and Inter-quartile range. 1x6=6
Ans: S.D: The standard deviation commonly denoted by ‘σ’ (Sigma) is the most widely used measure of dispersion. It is the square root of the second moment of dispersion and is calculated from the arithmetic mean. In short, it may be defined as the root-mean-square deviation from the mean.
Range:  Range is defined as the difference between the value of the smallest item and the value of the largest item included in the distribution. It is the simplest method of measuring dispersion.
Q.D: - The QD is half of the difference between the upper and lower quartiles. Symbolically, QD= ½ (Q3- Q1) QD is an absolute measure of dispersion.
M.D: For a given set of observation, MD is defined as the arithmetic mean of the absolute deviation of the observations from an appropriate measure of central tendency. The formula for computing MD is MD= ∑│D│/ N

27. What do you mean by environmental degradation? Suggest some measures to solve the problems of environmental degradation.                      1+5=6
Ans: The following strategies should be adhered to, for sustainable development:
1. Use of Non-conventional source of Energy like wind and solar says are cleaner and greener technologies, which can be effectively used to replace thermal and hydropower.
2. Use of CNG as fuel in public transport system has lowered air pollution and the air has become cleaner. The use of LPG and Gobar Gas is being promoted which reduces air pollution.
3. Establishment of Mini-Hydel plants in mountain regions to generate electricity through mini Hydel plants.
4. Wind Power: In areas where speed of wind is usually high, wind mills can provide electricity without any adverse impact on the environment. Wind turbines move with the wind and electricity is generated. No doubt, the initial cost is high. But the benefits are such that the high cost gets easily absorbed.
5. Solar Power through Photovoltaic Cells: India is naturally endowed with a large quantity of solar energy in the form of sunlight. We use it in different ways.
Explain briefly the following:    3+3=6
a) Demand-pull inflation.
Ans: Demand Pull Inflation: Inflation will result if there is too much spending when compared to output. Aggregate demand is greater than aggregate supply which leads to price hike and inflation. An increase in aggregate demand when the economy is at less than full employment level will result in an increase in both price and output. If the economy is at full employment then the demand will increase which leads to inflation.
b) Cost-push inflation.
Ans: Cost Push Inflation: Inflation is caused by change in the supply side of the economy, it increases cost of production, prices and inflation. Initially increase in costs leads to a chain of wage increases which leads to increase in demand and cost.
