A hairdresser owner gives a survey to all of her customers asking them to rate the quality of the service they received. She then keeps track of how many customers return to the salon during the next six months. Last year, the results showed that of the customers who reported high quality service, 95% returned. What conclusion can be drawn from this study?

1. High quality services cause customers to return. 2. Customers who will return report a high quality of service. 3. Only some customers rate their service as high quality return. 4. Most customers rate their service as high quality return.

what are your thoughts on this?

OpenStudy (anonymous):

well, i don't think it's a (since this is not a cause-and-effect study)

1*

jimthompson5910 (jim_thompson5910):

Hmm good point, but 95% of those who gave good marks came back so maybe it's not a guarantee, but it's pretty likely that if someone gives a good review, they will be coming back

This is part of a practice test, and another person who's taken it before and put 1 said they got it wrong

jimthompson5910 (jim_thompson5910):

"2. Customers who will return report a high quality of service." is slightly misleading. Those who come back may or may not report high quality. It will depend on the second experience they have. So just because they come back doesn't mean the second visit will have good marks

OpenStudy (anonymous):

yeah. and 2 makes it sound like they reported the high quality of service BECAUSE they came back

jimthompson5910 (jim_thompson5910):

the only thing left that fits is "4. Most customers rate their service as high quality return." so if they put high quality, then they are most likely to return

Thank you!

OpenStudy (anonymous):

Just the wording on these is terrible...

jimthompson5910 (jim_thompson5910):

agreed
