| A. When individual has choice to choose to participate. | I. Convenience |
| B. If sample gives less representation of the sample. | II. Response bias |
| C. When a sample is taken from individual that are conveniently available. | III. Voluntary response bias |
| D. Anything in a survey that influence responses. | IV. Undercoverage |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-III, B-IV, C-I, D-II
(A) When individual has choice to choose to participate.
This matches III. Voluntary response bias. People who choose to take part often have strong views, which biases the sample.
(B) If sample gives less representation of the sample.
This matches IV. Undercoverage. Some groups of the population are left out or under-represented.
(C) When a sample is taken from individual that are conveniently available.
This matches I. Convenience. The sample is chosen only because it is easy to reach.
(D) Anything in a survey that influence responses.
This matches II. Response bias. The way questions are asked, or other factors, affect the answers given.
So the matching is A-III, B-IV, C-I, D-II.
