Concept explainers
To explain how the sampling method results in under-coverage that could lead to bias.
Explanation of Solution
Households in the community which do not have telephones are not included in this sampling method. Households which do not have telephone would be poor, who cannot afford telephone or that households who are only using cell phones and do not have telephone. Here under-coverage occurs because in the population, there are some groups which are left due to the choosing of random sample. This sampling error leads to bias.
