A. choosing participants who will ensure that study results will support the hypothesis B. carefully selecting specific subjects who meet one s criteria from the population C. ensuring that every subject in the population has an equal chance to be selected D. using a survey to screen out participants who may interfere with other subjects

Answer 1

The correct answer is C.

The fairest way to take a representative sample from a population is to ensure that every subject in the population has an equal chance to be selected.

Because the fairest way means no one is being given priority over one another so every one should have the equal chance to vote or not or to fill in the sample or not.

All other listed options contain some sort of bias towards some category.
