Identify the type of sampling method used. A trucking company places their office phone number on the back of all of their vehicles to receive comments on how well their employees are driving.
This is an example of voluntary response sampling.
The type of sampling method used in this scenario is known as convenience sampling.
The sampling method used in this scenario is called "convenience sampling."
Explanation:
Convenience sampling is a non-probability sampling method where individuals are selected based on their easy availability and accessibility to the researcher. In this case, the trucking company is collecting feedback on their employees' driving skills by providing their office phone number on the back of all their vehicles. As a result, anyone who notices the phone number and calls it to provide feedback becomes part of the sample.
While convenience sampling is relatively quick and easy to implement, it may introduce bias since the sample may not be representative of the entire population. For instance, individuals who take the time to call and provide feedback may have strong opinions or may have had a particularly negative or positive experience, leading to a skewed representation of the overall employee driving performance.
