Class notes MATH 3450 Principles of Biostatistics Chapter 1

Document preview thumbnail
Preview 2 out of 9 pages

This introductory text on biostatistics provides a foundational framework for understanding how researchers gather and interpret data. It begins by distinguishing between populations and samples, while clarifying the difference between numerical parameters and calculated statistics. The material further categorizes data into qualitative and quantitative variables, offering specific examples to help students identify discrete versus continuous measurements. Readers are introduced to primary data collection methods, such as observational studies, controlled experiments, simulations, and surveys. Additionally, the notes detail various sampling techniques—including random, stratified, cluster, and systematic approaches—to ensure representative results. Finally, the source addresses the critical issue of systematic bias, specifically explaining how non-response and dishonest reporting can compromise the integrity of a study.
