🔍 What Is a Confidence Interval & Why Is It Important?

A confidence interval (CI) is a range of values that estimates where a population parameter (like a mean or proportion) is likely to lie, with a certain level of confidence (e.g., 90%, 95%, or 99%). It’s widely used in statistics, research, and data analysis to measure uncertainty and reliability in sample data.+

Whether you're a student analyzing survey data, a researcher conducting experiments, or a business professional interpreting market trends, confidence intervals help you make data-driven decisions with greater accuracy.
