Confidence Intervals

Confidence intervals are a fundamental concept in statistics that allow researchers to make inferences about a population based on a sample. They are used to estimate the range of values within which a population parameter is likely to fall with a certain level of confidence.

Why Learn About Confidence Intervals?

There are many reasons why someone might want to learn about confidence intervals. Some of the most common reasons include:

• To make inferences about a population: Confidence intervals can be used to make inferences about the characteristics of a population based on a sample. For example, a researcher might use a confidence interval to estimate the average height of all adults in a country.
• To test hypotheses: Confidence intervals can be used to test hypotheses about a population. For example, a researcher might use a confidence interval to test the hypothesis that the average height of all adults in a country is greater than 5 feet.
• To make predictions: Confidence intervals can be used to make predictions about future events. For example, a researcher might use a confidence interval to predict the number of people who will visit a website in the next month.
