Nonresponse occurs when a respondent is selected for the survey but does not provide any data. This can happen when a household does not return the survey form and cannot be reached by telephone. Undercoverage is when some members of the population are not represented in the sample, which is not the case here. Simple random sampling and volunteer bias are not relevant to this scenario.
