Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A and C only
A population is the whole collection of elements that share the characteristic under study, and in inferential statistics conclusions are drawn from a sample about the population.
Checking the statements
(A) It is a collection of all elements having same characteristics — Correct. This is the definition of a population.
(B) A survey done on the total population is not accurate — Incorrect. A survey of the whole population covers every element, so it is accurate; its drawbacks are cost and time.
(C) Population focuses on the identification of the characteristic — Correct. The population is defined by the characteristic that its elements share.
(D) Population focuses on drawing inference about the sample — Incorrect. The inference is drawn from the sample about the population, not the other way round.
