A sample of 50 students is to be chosen from a school in such a way that every student of the school has an equal chance of being selected. Which method of sampling is this?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Random sampling
In random sampling, every individual of the population has an equal chance of being selected, for example by drawing names by lottery. In judgement, quota and convenience sampling the investigator’s choice decides who is selected, so these are non-random methods.
