Successful students attend classes regularly. They are on time. They listen and train themselves to pay attention. If they miss a class, they feel obligated to let the teacher know why before class begins, if possible, and their excuses are legitimate and reasonable. They make sure they get all missed assignments (by contacting the teacher or another student), and understand specifically what was covered in class. Successful students take responsibility for themselves and their actions.

Explanation:
In survey sampling exists something called Non-response bias, occurs when people selected to complete a survey are unable to do it. In some cases, they are too busy, unwilling, or just don't like completing surveys. Indeed, Nonresponse bias usually occurs when the ones who responded are different in many ways from nonrespondents. With a response rate around 10%, the results are not trustworthy, skewing too much the information obtained in the collected surveys.
