Which choice best describes a simple random sample?

a. a selection of members from a population in such a way that every possible sample of the same size has an equal chance of being chosen.
b. when a population is first sorted into comparable groups, groups are randomly chosen, and all of the individuals from those groups are chosen.
c. a selection of members of a population chosen because of their convenient accessibility and proximity.
d. a selection of members chosen from a population beginning at a random point and then chosen at set intervals from that point.
e. when a population is first sorted into groups that share a similar characteristic and individuals are randomly chosen from each of the groups.

a. a selection of members from a population in such a way that every possible sample of the same size has an equal chance of being chosen.

Step-by-step explanation:

In the process of simple random sampling, a subset of the population is directly randomly chosen from the whole population, without dividing the population in groups (like in cluster sampling), without taking proximity into account (like in convenience sampling) or using set intervals (like in stratified sampling). In simple random sampling, every possible subset of the same size has the same probability of being selected.

Therefore, the statement that better fits this description is alternative a.
