Identify the sаmpling technique used in the fоllоwing infоrmаtion. Suppose you аre conducting a survey to study the commuting patterns of residents in a metropolitan area. You want to understand the modes of transportation used by residents, including carpooling, public transportation, cycling, walking, and telecommuting. You plan to survey 200 residents across different neighborhoods using various sampling techniques. Categorize each technique as a simple random sample, stratified sample, systematic sample, cluster sample, or convenience sample. Group the residents based on their workplace location: downtown, suburban business parks, industrial areas, residential neighborhoods, and remote work setups. Then randomly select 10 residents from each workplace location category for the survey.
