Explanation:
Geometric mean = (4 × 9 × 16)^(1/3) = (576)^(1/3) = 8. It is the nth root of the product of n observations, useful for averaging ratios or growth rates.
Assertion (A): Primary data collection is generally more time-consuming than secondary data collection. Reason (R): Primary data requires designing instruments, sampling, and fieldwork, whereas secondary data is readily available.
A.Both A and R are true, but R is not the correct explanation of A
B.A is true but R is false
C.Both A and R are true, and R is the correct explanation of A
Explanation:
Primary data collection involves extensive planning, instrument design, sampling, and field execution, making it inherently more time-intensive than accessing pre-existing secondary data.
