Question

10) Suppose a high school guidance counselor wants to find out the proportion of students at his high school who have tried alcohol. He sends out an email to 200 randomly selected students asking them if they have tried alcohol. out of the 92 that responded, 6% said they had tried alcohol. Describe how nonresponse might lead to bias in this study * Your answer​

Answer 1

Answer:

A nonresponse might lead to a bias in the study due to the fact that the counselor may assume that those who did not reply to the email may have tried alcohol and they didn't want him(the counselor) to know.

Step-by-step explanation:

In statistical research, a bias is said to occur when systematic errors are introduced into sampling or testing by selecting or favoring one outcome over other outcomes.

Now, applying that definition to this question, we can say that a nonresponse might lead to a bias in the study due to the fact that the counselor may assume that those who did not reply to the email may have tried alcohol and they didn't want him(the counselor) to know.
