Paper 1 · Research Aptitude
In a research with a small total population, each element is numbered on separate slips, all slips are put in a box, and the researcher picks them out one by one without looking until the desired sample size is reached. This technique is called
AThe snowball sampling method
BThe fishbowl sampling method ✓ Correct
CThe stratified sampling method
DThe cluster sampling method
Correct answer: (B) The fishbowl sampling method — Drawing numbered slips from a box until the sample is filled is the fishbowl sampling method, so that is the answer.
Explanation
★Drawing numbered slips from a box until the sample is filled is the fishbowl sampling method, so that is the answer.
★The fishbowl method mixes numbered slips in a container and draws them at random.
★So it is a simple, hands-on way of taking a random sample from a small population.
★Snowball sampling grows the sample through referrals, not from a box of slips.
★Stratified sampling first divides the population into strata, which is not done here.
★Cluster sampling selects whole clusters, so drawing slips from a box is the fishbowl method.
