Question

With reference to time series, match List I with List II

	LIST I		LIST II
A.	Secular movements	I.	Price increase before Deepavali
B.	Seasonal variations	II.	Increase in price of gold during a major war
C.	Cyclic variations	III.	Long term trends
D.	Irregular variations	IV.	Recurring rise and decline in production

Choose the correct answer from the options given below:

• A. A-III, B-I, C-IV, D-II
• B. A-II, B-I, C-IV, D-III
• C. A-III, B-II, C-IV, D-I
• D. A-II, B-III, C-IV, D-I

Answer 1

The Correct Option is A

To match List I with List II in the context of time series, consider the descriptions provided:

1. Secular movements: These refer to long-term trends observed over years or decades. They are not tied to any specific cyclic event but show a general direction over time, such as growth or decline. Match: III. Long term trends
2. Seasonal variations: These are predictable changes that recur annually, often due to climate or cultural events. For example, prices rising before a festival like Deepavali reflects such variation. Match: I. Price increase before Deepavali
3. Cyclic variations: These occur over several years, showing a pattern of rise and fall. Unlike seasonal variations, they are not tied to a calendar cycle but occur over longer intervals, typically tied to economic cycles. Match: IV. Recurring rise and decline in production
4. Irregular variations: These are unpredictable changes due to unforeseen events such as wars, floods, etc. Their occurrence and impact do not follow a predictable pattern. Match: II. Increase in price of gold during a major war

Thus, the correct matching is: A-III, B-I, C-IV, D-II.
