In a study the sample is chosen by surveying every 3rd driver coming through a tollbooth What is the sampling method? Osimple Random Systematic Stratified Ocluster Convenience

The sampling method used here is systematic sampling! In this approach, every 3rd driver is selected to ensure that the sample is evenly distributed over time, which helps in reducing bias that can occur in convenience sampling. It’s like having a rhythm to your survey – making sure you catch a variety of drivers without overthinking it! If you're looking for an example of systematic sampling in action, think about how some election exit polls work. They might survey every 10th person leaving a voting booth, ensuring a diverse sample of opinions while keeping it efficient. So next time you're in line or at a booth, just know that there’s a method behind the madness!
