Question

Which of the following is not a form of bias? Multiple Choice Portions of the population are excluded or underrepresented from the sample. Information from the sample overemphasizes a particular stratum of the population. Those responding to a survey or poll differ systematically from the nonrespondents. Certain groups in the population are systematically underrepresented in the sample.

Answer 1

B. Information from the sample is typical of information in the population.

Explanation:

In Statistical Research, a Bias refers to the tendency of a sample statistic to systematically overestimate or underestimate a population parameter.

(A)When portions of the population are excluded or underrepresented from the sample, it is a Sampling Bias.

(C)When those responding to a survey or poll differ systematically from the nonrespondents, it is referred to as Non-Response Bias.

(D)When certain groups in the population are systematically underrepresented in the sample, it is referred to as Selection Bias.

Therefore option B is not an example of a Bias.
