An educаtiоnаl technоlоgy firm is seeking feedbаck on a new learning platform from schools nationwide. Given the vast number of schools, they opt for a sampling method. They divide the schools into groups based on the type of school district they are in (urban, suburban, rural). They then randomly select whole districts and include all schools within the selected districts in the survey. This method saves time and resources as the firm can visit only some schools across all districts. Please identify the sampling method.
