https://youtu.be/E77PYuEEbr4 Learn how to interpret confidence intervals correctly. Understand if your data results are truly statistically significant. Understanding confidence intervals is essential for clear data analysis. This tutorial breaks down the core concepts using a practical example involving cortisol levels to demonstrate how researchers determine range estimates for their findings. We walk through a specific case where the mean difference in cortisol is 6 mg per deciliter, with a 95% range between 2.5 and 9.5. You will learn why excluding zero from this interval confirms statistical significance in your study results.
