This is nonresponse bias because many customers may choose to not fill out the cards
O This is question wording bias because the customer service score levels may not be clear to customers.
O This is response bias because customers may not be truthful about their experience with customer service.

Answer 1

The likelihood of nonresponse bias is high in the automotive service center's customer feedback survey since it's based on voluntary participation, which may not accurately represent all customer opinions.

Step-by-step explanation:

The automotive service center is collecting customer feedback through a short survey, with an average satisfaction score of 2.47 based on 140 filled out cards. The most likely type of bias in these survey results would be nonresponse bias. Nonresponse bias occurs because many customers may choose not to fill out the cards, hence the collected data may not represent the views of all customers. Those who had a particularly negative or positive experience may be more inclined to complete the survey, while those with moderate views may not bother, skewing the results.

Answer 2

"This is nonresponse bias because many customers may choose to not fill out the cards"
Not everyone will chose to leave a review when leaving the store, and those that do were probably in some way inconvenienced, and felt inclined to leave one, while the others left and went about their day.
