Learn How to Analyze, Interpret, and Make Sense of Data in Everyday Life

In an era where data fuels everything from personal decisions to global policy, being data-literate is no longer a luxury — it’s a necessity. Whether you're evaluating news headlines, monitoring your health, or running a business, the ability to understand and interpret data is a skill that empowers better decisions.
