What type of bias is indicated by each of the following? If there is not bias, then put down 'no bias'.
a Portions of the population are excluded from the sample.
b Information from the sample is typical of information in the population.
c Information from the sample overemphasizes a particular stratum of the population
d Those responding to a survey or poll differ systematically from the nonrespondents.
a. The type of bias that will occur in the given sample would be undercoverage bias because the people who are excluded from the sample are a part of the population but they are inadequately excluded.
b. The type of bias that will occur in the given sample would be nonresponse bias because the sample is typical of information in the population that means the respondents and nonrespondents will differ from each other significantly due to the difference in sample information and population information.
c. The type of bias that will occur in the given sample would be voluntary bias because a particular stratum is overemphasized hence that sample will overrepresent the individuals in that particular stratum.
d. The type of bias that will occur in the given sample would be nonresponse bias because the respondents differ from nonrespondents in a meaningful way.
Good luck with your studies!!!
