Data science is an interdisciplinary field that seeks to find interesting generalizable insights within data and then puts those insights to monetizable use. In this 8-video Skillsoft Aspire course, learners can explore the first step in obtaining a representative sample from which meaningful generalizable insights can be obtained. Examine basic concepts and tools in statistical theory, including the two most important approaches to sampling-probability and nonprobability sampling-and common sampling techniques used for both approaches. Learn about simple random sampling, systematic random sampling, and stratified random sampling, including their advantages and disadvantages. Next, explore sampling bias. Then consider what is probably the most popular type of nonprobability sampling technique-the case study, used in medical education, business education, and other fields. A concluding exercise on efficient sampling invites learners to review their new knowledge by defining the two properties of all probability sampling techniques; enumerating the three types of probability sampling techniques; and listing two types of nonprobability sampling.
