A confidence interval is a statistical tool used to estimate the range of values within which a population parameter is likely to fall. It is a key concept in statistical inference, allowing researchers to make conclusions about a larger population based on a smaller sample. The confidence interval provides a level of certainty or confidence about the accuracy of the estimate.

Also known as confidence intervals, these statistical measures are widely used in various fields such as economics, social sciences, and health research. They are essential for decision-making, policy formulation, and understanding the true nature of data.

A confidence interval provides a range of values within which the true population parameter is likely to lie. It is determined by factors such as sample size, variability, and the desired level of confidence. The wider the interval, the less precise the estimate, while a narrower interval indicates a more precise estimate.
