Covariance measures how two variables move together: whether they rise and fall in sync or move in opposite directions. In this video, we build intuition for what covariance means, walk through the formula step by step, and calculate it by hand with a simple example. We also explore how covariance plays a role in finance, physics, machine learning, and data analysis. This is a foundation you'll need before learning about correlation and multivariate analysis.
