To find how high school students feel about hot lunches, Adam walks to the nearest high school and
gives a survey postcard to every twentieth student that enters the building. He asks the students to mail
the postcard in if they choose to participate in the study.
Why might the method used be biased?
Asking every twentieth student does not accurately represent the student population.
It is likely that student opinions in one particular high school do not accurately represent the opinions
of all high school students.
Students that take the time to complete the survey and mail it in probably feel strongly about hot
lunches.
