Designing a Sampling Program,The first and most important step of any environmental study is to design the sampling program. This chapter discusses the basics of designing a sampling program, and shows you how to use EnvStats to help you determine required sample sizes. For a more in-depth discussion of sampling design and sample size calculation, see Millard et al. (2014).作者: 吊胃口 時(shí)間: 2025-3-25 23:28
