In online surveys, which of the following are sampling issues ? A. People in a household may use the same computer, as they have access to only one. Choose the most appropriate answer from the options given below :
B. Many respondents may have multiple email IDS.
C. Internet users constitute a biased sample of the population
D. Sampling frames for online surveys are cheap.
E. The governments restrict online surveys.
A, B and C only
This question asks which statements describe genuine sampling problems in online surveys. A sampling issue is anything that distorts who ends up in the sample or how well the sample represents the target population.
Consider each statement:
A. People in a household may share the same computer because they have access to only one — this is a sampling issue: a single device can under-represent individuals, since one response may stand for several people or one person may dominate access.
B. Many respondents may have multiple email IDs — this is a sampling issue: a person with several email addresses can be selected more than once, causing duplication and over-representation.
C. Internet users constitute a biased sample of the population — this is a clear sampling issue (coverage bias): people without internet are excluded, so the sample is not representative of the whole population.
D. Sampling frames for online surveys are cheap — low cost is a practical advantage, not a sampling problem, so it does not belong.
E. Governments restrict online surveys — this is a regulatory or access barrier, not a defect in how the sample represents the population.
Hence only A, B and C are sampling issues.
Why the other options are wrong: any combination that includes the low cost of sampling frames or government restriction mixes an advantage or an external constraint in with true representativeness problems, so it cannot be the set of sampling issues.
Takeaway: online sampling issues concern coverage bias, shared devices and duplicate identities, not cost or legal limits.
Correct answer: A, B and C only
