What Is A P-value In Scientific Claims? - Philosophy Beyond

Описание: What Is A P-value In Scientific Claims? Have you ever wondered how scientists determine whether their experimental results are meaningful or just due to chance? In this informative video, we'll explain everything you need to know about the concept of a p-value in scientific claims. We'll start by defining what a p-value is and how it helps researchers interpret their data. We'll discuss how p-values are used to assess the likelihood of observing certain results if there is actually no real effect, and what the common threshold of 0.05 means in practice. You'll learn about the difference between statistical significance and practical importance, and why a small p-value doesn't necessarily prove an effect is real or meaningful. We'll also explore the philosophical questions surrounding the interpretation of evidence, emphasizing that p-values only measure how compatible data are with the null hypothesis, not the probability that the hypothesis is true. Additionally, we'll highlight common mistakes scientists and researchers make when interpreting p-values, such as overreliance on a single number without considering effect sizes or confidence intervals. Whether you're a student, researcher, or curious mind, understanding the limitations and proper use of p-values is essential for making informed conclusions from scientific data.
