To find: The type of sample described here. Also, explain if the sample is biased or not.
The type of sample is systematic and it is unbiased.
Given:
A taxicab company asks each driver to perform survey on every 10th customer of the day to know if customers are satisfied with the service or not.
Explanation:
Systematic sampling is a type of sampling in which every
Since, survey is being performed by drivers on every 10th customer, it means sampling is being done at the regular interval. Thus, it is systematic sample.
The sample is unbiased because ccustomers of the cab company are being equally represented as a group.
