Question

a. pollster interviews
b. mail questionnaires
c. in-person interviews
d. telephone interviews

I can't find this answer anywhere in my textbook. Help!

Answer 1

Mail in are self-selecting. Wasn't that one of the errors in the Truman-Dewey race in 1948?

Answer 2

This explains how samples are selected for polling. Yes, mail-in (and phone-in) samples are self-selecting and not representative of the larger population.

Answer 3

I thought it doesn't matter if they are self-selecting or not for this question

Answer 4

Can someone help me please I don't understand

Answer 5

You can't have a self-selecting poll for it to be representative.

Answer 6

What is the difference between a pollster interview and an in-person interview?

Answer 7

I tried to find out online. What does your text say?

Answer 8

It doesn't mention pollster interviews at all.

Answer 9

I vote for b.

Answer 10

I would pick B because it is not modern at all and I do not think it is even used seriously any more.

Answer 11

Mail-in and call-in surveys are, as noted, considered unreliable, unrepresentative. TV channels do use call-in polls; they are not taken seriously. Mail-in polls may be used, but are meaningless. Reputable polling organizations do not use those methods.

Answer 12

I, too, have no idea what the A choice means as differentiated from C and D. C and D are both pollster interviews. In any case, A, C, and D are considered valid ways to conduct polls.

Answer 13

Thanks for all the answers
