IHP-525 provides students with a basic foundation of biostatistics and its role in public health and health sciences. The course covers the statistical principles that govern the analysis of data in public health and health sciences, including exploratory data analysis, probability theory, confidence interval testing, hypothesis testing, power and sample size determination, and multivariable methods.
Statistical foundations for health data
The course builds the core statistical toolkit — probability theory, confidence intervals, hypothesis testing — specifically applied to public health and health science data, rather than teaching statistics as an abstract mathematical subject.
Power, sample size, and multivariable methods
IHP-525 covers power and sample size determination (ensuring a study is designed to actually detect a real effect if one exists) and multivariable methods (accounting for multiple factors simultaneously), both essential for credible health research design.
Key topics in IHP525
- Exploratory data analysis for health data
- Probability theory in biostatistics
- Confidence interval testing
- Hypothesis testing
- Power and sample size determination
- Multivariable statistical methods

Worked example: why sample size determination matters before data collection
- Underpowered study: A study with too small a sample size fails to detect a real effect that actually exists
- Properly powered study: Sample size is calculated in advance to ensure the study can reliably detect a meaningful effect
- Lesson: IHP-525 teaches that sound biostatistics starts before data collection even begins, with rigorous sample size planning

Frequently asked questions
Public health and health science data present specific challenges — study designs involving human populations, ethical constraints on experimentation, and outcome measures like disease incidence — that general statistics courses don't always address directly, and applying statistical principles to these health-specific contexts (like confidence intervals for a disease prevalence estimate) builds more immediately useful competency than abstract statistical theory. IHP-525 grounds its content in health science application because that's the context in which students will actually use these statistical skills.
A study that's already been conducted with too small a sample size may simply be unable to detect a real effect even if one genuinely exists, wasting the research effort and potentially leading to a false 'no effect' conclusion, so determining adequate sample size before data collection begins is essential to designing research capable of producing meaningful, trustworthy results. IHP-525 covers this because sound biostatistics starts with proper study design, not just after-the-fact data analysis.
