This lesson is part of EHS 212 Biostatistics , a 2-unit course designed for Environmental Health Science students. This expanded series focuses on Non-Random Sampling Methods — a critical component of research methodology in public and environmental health. Non-random sampling refers to sampling techniques that do not give every member of a population an equal chance of being selected. These methods are widely used in health research when probability sampling is impractical, time-consuming, or cost-prohibitive. Students will explore the theoretical foundations of non-random sampling, understand when and why it is applied in real-world health research settings, and critically evaluate its strengths and limitations.
This course introduces students to the fundamental principles of biostatistics as applied in environmental and public health sciences. It equips students with the quantitative skills necessary to collect, organize, analyze, and interpret health-related data. Series 2 focuses specifically on Sampling Techniques and Data Distribution — two core pillars of statistical reasoning in biostatistics research.
