There is no simple answer to the question, "how large a sample should I take?" Sample size depends on various data collection design details and on how we intend to use the data in future decision making. But with careful thought and some basic statistical knowledge, even nonstatisticians can determine the appropriate sample size for achieving useful results from data collection efforts.
对于“我应该选取多大的样本？”这个问题，没有简单的答案。样本大小取决于各种数据收集设计细节以及我们打算如何在未来决策中使用这些数据。但是，通过仔细思考和一些基本的统计知识，即使是非统计学家也能够确定合适的样本大小，以便从数据收集工作中获得有用的结果。
