Many delivery trucks feature a "How Am I Driving?” sticker on the rear bumper, along with a phone number. This sticker allows drivers to report erratic driving by the truck driver or offer a compliment if they like. A dispatcher at the trucking station accepts calls and records information from those who call the phone number. The dispatcher reports that in the past month, 218 calls were received. Of those calls, 178 reported negative driving behaviors by the truck drivers. How might this data-collection method produce bias in obtaining an estimate of all drivers who are satisfied with the company’s truck drivers?

To join Kindling, she was required to reveal her private information such as complete name, location, contact details, the school she went to, the companies or places she worked for, etc. These data will eventually be shared by Kindling users, users’ friends or the dating website itself.

As part ofhis yearly report to the CEO, he is required to present an analysis of the salariedemployees. Because there are over 1,000 employees, he does not have the staff to gatherinformation on each salaried employed, so he selects a random sample of 30 (Fred G. Hireworksheet). For each employee, he records monthly salary; service at Crescent, inmonths; gender (1 = male, 0 = female); and whether the employee has a technical orclerical job.
