Statement I: Online surveys are very useful because internet users always constitute an unbiased sample of the population.
Statement II: A convenience sample is one that is simply available to the researcher by virtue of its accessibility.

Both Statement I and Statement II are incorrect
- C.
Statement I is correct but Statement II is incorrect
- D.
Statement I is incorrect but Statement II is correct
Show answer & explanation
Correct answer: D
Concept
Representativeness depends on how sampling units are selected and covered, not merely on whether a survey is administered online.
Convenience sampling is a non-probability method that selects units because they are readily accessible to the researcher.
Application
Statement I uses the absolute word always. An internet-only frame can exclude non-users and can attract self-selected respondents, so internet users do not necessarily form an unbiased population sample.
Statement II describes selection by ready accessibility, which is the defining basis of a convenience sample.
Contrast
Both statements correct: this overlooks coverage and self-selection bias in online recruitment.
Both statements incorrect: this rejects the accessibility-based definition of convenience sampling.
Statement I correct and Statement II incorrect: this reverses both sampling judgments.
Statement I incorrect and Statement II correct: this keeps survey-mode bias separate from the accessibility-based sampling method.
Result
Therefore, Statement I is incorrect but Statement II is correct.
