How Does Pre-Specification Impact P-Value Interpretation?

Описание: Ever wondered how planning your statistical analysis before seeing the data can dramatically change what your p-values actually mean? This video dives deep into the crucial role of pre-specification and its profound impact on interpreting statistical significance.

In this insightful discussion, we uncover:
► The fundamental concept of pre-specification in research design and why it's essential for robust scientific inquiry.
► How failing to pre-specify hypotheses can inflate Type I error rates and lead to spurious significant findings.
► The distinction between confirmatory and exploratory analyses and how pre-specification clarifies their respective roles.
► Practical implications for researchers and consumers of scientific literature regarding the trustworthiness of p-values.
