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 described in your problem is **Systematic Sampling**. Here's the reasoning: 1. **Simple Random Sampling**: Every individual has an equal chance of being selected. This is not the case here since every 3rd driver is chosen. 2. **Systematic Sampling**: This method involves selecting every nth individual from a list or sequence. In this case, every 3rd driver is being surveyed, which fits this definition. 3. **Stratified Sampling**: This involves dividing the population into subgroups (strata) and then taking a sample from each stratum. This is not applicable here. 4. **Cluster Sampling**: This involves dividing the population into clusters and then randomly selecting entire clusters. This is also not applicable. 5. **Convenience Sampling**: This involves selecting individuals who are easiest to reach. This method is not used in your scenario. Thus, the correct answer is **Systematic**.
