For the scenarios below, determine which sampling method was used (simple random, cluster, convenience, stratified, systematic), and
briefly
state how you were able to identify the type of sampling being used.
Please note: each sampling method will be used only once.
-A student surveys 30 people who happen to be on campus at 1:00 pm on a Monday.
-Students are divided into groups by number of years at the college, and then a simple random sample is drawn from each group.
-Students are divided into groups based on income level, 3 income levels are randomly selected, and all students within the selected income groups are surveyed.
-50 students are selected by using their student ID numbers, and a random number generator.
-Students are selected by selecting every 10th
name off of a list of all current students at STS.
