Question

the president of the math club is conducting a survey to see where the twelfth - grade class wants to go on their field trip. instead of asking the whole class, she surveys only the twelfth - grade members of the math club. she records their choices and plans to present the results to the school principal. what type of sampling did she use?
o systematic random sampling
o simple random sampling
o stratified sampling
o convenience sampling

Explanation:

Convenience sampling involves selecting individuals who are easily accessible. Here, the math - club president surveys only the twelfth - grade members of the math club, which is a convenient group for her to reach rather than the entire twelfth - grade class. In systematic random sampling, there is a fixed sampling interval. In simple random sampling, every member of the population has an equal chance of being selected. In stratified sampling, the population is divided into strata and samples are taken from each stratum.

Answer:

D. convenience sampling
