Setting Sample Size
Setting Sample Size
This chapter begins our discussion of how to control sampling error by discussing how to set sample size. As we will see, the level of sampling error is determined by the sample size, which means that sample sizes can be calculated to produce acceptable levels of sampling error. In this chapter, you will learn the following:
- How sampling error relates to sample size
- How to calculate a sample size that provides an acceptable level of sampling error
- How to calculate a sample size based on hypothesis testing power
- How to calculate a sample size based on the value of information
- Informal methods for setting sample size
The discussion in this chapter presumes the use of simple random sampling. In some situations, it may be possible to make ...
