Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
The items are the components of a time series.
(A) Decrease in production due to fire in a factory
This matches (III) Irregular trend.
A fire is an accidental, unpredictable event, so its effect is an irregular (random) variation.
(B) Woolen clothes sales are higher in winter.
This matches (I) Seasonal trend.
The rise repeats every year with the season, a seasonal variation within a year.
(C) Rise and fall of the share market.
This matches (IV) Cyclical trend.
Periods of boom and depression that last longer than a year are cyclical variations.
(D) Continuous increase in population
This matches (II) Long term trend.
A steady movement in one direction over a long period is the secular (long-term) trend.
So the matching is (A)-(III), (B)-(I), (C)-(IV), (D)-(II).
