Biostatistics and Summary Statistics for Public Health

Public health decisions rely heavily on data, but raw numbers are meaningless without the tools to summarize and interpret them. Understanding the fundamentals of biostatistics is key to unlocking insights from health studies, clinical trials, and medical literature. This text-based course guides you through the foundational concepts of summary statistics, enabling you to confidently read, analyze, and apply statistical measures to real-world public health scenarios. You will transition from looking at complex datasets to extracting clear, actionable metrics that inform health policies and research. What you'll learn: - Understand core biostatistical terminology and the different types of public health data. - Calculate measures of central tendency, including mean, median, and mode, to describe health populations. - Measure data variability using range, variance, standard deviation, and percentiles. - Interpret statistical summaries and epidemiological metrics from published scientific literature. - Apply modern tidy data principles to organize health datasets for accurate statistical analysis. - Identify common statistical pitfalls and reporting biases in modern public health reporting. The course begins with foundational definitions of variables and data types before moving into practical calculations of dispersion and central tendency. You will progress to analyzing actual public health studies, learning how to critically evaluate statistical summaries in written scientific contexts. This course is designed for beginners, including aspiring public health professionals, researchers, and students with no prior background in advanced mathematics or statistics.
