Suppose you are conducting a survey regarding illicit drug use among teenagers in some school district. you obtain a cluster sample of 12 schools within the district and sample all sophomore students in the randomly selected schools. the survey is administered by the teachers. nothing nothing

Based on the scenario, I believe the survey might contain A  Response bias

and one of the things that can be done to fix this is to perform the polling by professional social workers

Explanation:

Response bias refers to a situation where the subject in a research have some sort of push or incentives to falsify the data that they give to the researchers.

Let's review the scenario above.

When teenagers are asked about their experience to use drugs , it is very likely that they will lie to the researchers because they fear that they could get in troubles with their parents or with the law. This will create a response bias.

Performing the polling by using social workers can help to encourage them to tell the truth by guaranteeing the secrecy of their answers.

1. seasonal

2. frictional unenployment

3. the number of the labor force multiplied by 100 and then subtract the number of unemployed.

4. 4%

5. an increase in prices

i think it is the third one.
