Question 1

Give an example on sampling bias.

Accepted Answer

Students' answers may vary.A poll conducted online by a newspaper asking for "the public's" opinion about some local issue will certainly not represent "the public" since those without access to computers or the internet,those who do not read that paper's website,and those who do not have the time or interest will not answer the question.
