What this course is about
Statistics is not only a collection of calculations. It is a language for learning from observations, expressing uncertainty, and deciding which scientific claims the available evidence can support.
The eight lessons in stats4PT follow that movement from observations toward claims. They connect statistical inference with causal reasoning, Bayesian updating, mechanisms, and the critical evaluation of research in physical therapy.
Before you begin
- No advanced mathematics is required.
- Read the lessons in order for the clearest progression.
- Focus on the assumptions behind a method, not only its output.
- Keep a clinical or research question in mind as you work.
The learning path
The course begins by asking how observations become statistical claims. It then distinguishes association from causation, introduces general Bayesian reasoning, applies Bayesian updating to diagnosis and prognosis, and then examines Bayesian methods in research and evidence synthesis. It next asks when population evidence applies to an individual, makes causal assumptions visible with diagrams, and concludes with common fallacies and biases.
Certificate pathway
Learners who complete all eight lessons, interactive activities, and reflection prompts may request access to a cumulative final examination. Participants who complete the examination independently and earn a passing score can receive a certificate of completion documenting 8 contact hours of professional learning.
All lessons and learning activities are freely available. The optional certificate pathway has a $49 fee, which covers access to the cumulative examination, scoring and review, completion-record retention, and preparation and delivery of an individually issued certificate. The fee includes the initial assessment and one retake. Payment does not guarantee a certificate; participants must earn a passing score.
To request access after completing the course, contact Sean Collins.
