What Is The Difference Between P-value And Alpha Level? - The Friendly Statistician
What Is The Difference Between P-value And Alpha Level? In this informative video, we will clarify the concepts of P-value and alpha level, two key components in the realm of statistics and hypothesis testing. Understanding these terms is vital for anyone looking to interpret research findings accurately. We will begin by defining what a P-value is and how it is used to evaluate the strength of evidence against the null hypothesis. You’ll learn how researchers calculate this probability based on their data and why a lower P-value can indicate stronger evidence. Next, we will discuss the alpha level, which serves as a predetermined threshold set before any data collection takes place. This level is essential in determining the risk of making a Type I error, which occurs when a researcher mistakenly rejects a true null hypothesis. We will explain why an alpha level of 0.05 is commonly used and what it means for the research process. By the end of this video, you will have a clearer understanding of how P-values and alpha levels work together in hypothesis testing. Whether you are a student, researcher, or simply someone interested in statistics, this video will provide valuable information to enhance your comprehension of statistical significance.
