This is called a probability sample because every household in the population has an equal chance of being selected for the interview. It is not a convenience sample because the manager is not choosing households based on ease or convenience, and it is not a stratified sample because the households are not being divided into groups based on certain characteristics before being selected. Sampling error refers to the amount of error or variability that can occur when a sample is selected from a population, so it is not applicable to describing the method used by the research manager.
