 Click here to see ALL problems on Miscellaneous Word Problems Question 185685This question is from textbook saxon algebra 2 : A manager gives a store evaluation form to each customer. Customers who mail in their complete forms receive a coupon. Identify the type of sample and determine whether it is biased. Explain your answer. I'm thinking this is a Self-selected sample. Am I correct? I'm not sure if it is biased or not. Maybe it's biased because only those customers mailing in the completed forms get a coupon. Any thoughts on this?This question is from textbook saxon algebra 2 Answer by stanbon(57984)   (Show Source): You can put this solution on YOUR website! Yes, it has self-selective bias. The bias is that participants choose themselves as participants. The coupons are simply a motivator but are not the reason for the bias since everyone who receives a survey has the same motivation. ---------------------------------------- Cheers, Stan H.
