Alpha value and Type I error are foundational concepts in biostatistics and clinical research interpretation.

In this lecture on This Is Why, Dr. Busti will explain what alpha represents, how it is determined, and how clinicians should interpret it when evaluating medical literature. This session clarifies the relationship between alpha, Type I error, hypothesis testing, and study power, helping learners connect statistical theory to real clinical decision-making.

This lecture is part of the broader This Is Why evidence-based medicine series, where each concept builds on previous topics to strengthen your ability to critically evaluate research.

Be sure to explore the full playlist to connect concepts like hypothesis testing, power analysis, and statistical errors.

Topics Covered:

- Definition of alpha in clinical research

- Alpha as probability of Type I error

- Interpreting alpha in published studies

- One-tailed vs two-tailed hypothesis testing

- Relationship between alpha and study power

- Type I error vs correct decision-making
