Demystifying P Values - Simple Explanation

Unlock the mystery of p-values and their critical role in evaluating evidence in experiments! In this video, we break down the concept of p-values, explaining their probability-based nature and why they're essential for determining the statistical significance of research findings. Learn about the null hypothesis, illustrated through a courtroom analogy and a practical example of testing a new drug versus a placebo. Discover how to assess the fairness of a coin using p-values and understand the significance level (alpha), including the common 0.05 threshold. Finally, we'll explore the practical versus statistical significance of p-values and the impact of sample size.
