Let's do the activity!
Justin Timberlake’s concert promoter wants to find out how much fans in the V.I.P. section enjoy the concert. He will estimate the average enjoyment level (1 to 100) for all 50 fans by selecting a sample of 10 fans.
Method #1: Simple Random Sample
Assign each fan a number. Randomly select 10 of the numbers.
Interview fans assigned the 10 selected numbers.
Method #2: Cluster Sample
Each row is a cluster. Randomly select one row.
Interview all fans in the selected cluster.
Method #3: Systematic Sample (every 8th)
Randomly choose a fan as a starting point.
Move down rows to interview every 8th fan.
After last row, wrap back around to the first row.
