Question
(8.04) You see a woman student standing at the parking lot entrance , stopping all students to ask them questions. She says that she is collecting student opinions about parking for students on campus. What is the most correct statement about this sampling method? This type of sampling is generally good. The method is bad because the choice of respondents is biased. This is not sampling at all. The method is not good because it is a convenience sample. The method is bad because of the location of survey. The sampling method is quite good for this question.
Explanation / Answer
It is a convenience sample; she is only getting opinions from students who are at the student parking at a certain time of day. This might underrepresent some group of the people. Here these students can't represent the entire population of the school/college but in most cases, the population is just too large that it is impossible to include every individual. This is the reason why most researchers rely on sampling techniques like convenience sampling, the most common of all sampling techniques. Many researchers prefer this sampling technique because it is fast, inexpensive, easy and the subjects are readily available.
