Chapter 8.2, Problem 37E

To determine

Explain some of the possible source of error that is not included in the margin of error.

Answer to Problem 37E

Selection bias, response bias and nonresponse bias are three source of error that does not included in the margin of error.

Explanation of Solution

The possible source of error that is not included in the margin of error are

While taking a survey some parts of the population can be excluded. This is called selection bias.

Survey result can gives different values from the true value. This is called response bias.

Also it is very difficult to collect data for everybody in the sample. This is called nonresponse bias.

Hence, three source of error that does not included in the margin of error are selection bias, response bias and nonresponse bias.
