d. None of the above
Continuation of part 2. A research administrator accidently records data obtained from the above survey incorrectly. This is an example of?
a. Sampling error
b. Human error
c. Response bias
d. None of the above
Explanation / Answer
Part 1) The results of the sample conform (are similar) to the the population. Hence, we can say that the sample is a good representative of the data and there is negligible sampling error. Thus, Option 4 (None of the Above).
Part 2) Here, the participant has misleadingly answered the question, which is an example of Response Bias.
Part 2)b) here the administrator accidently records incorrect data, which falls under Human Error.
