What Are Confidence Intervals?

Recommended for you
• Select a sample from the population of interest.
• Data analysts and scientists

Some common misconceptions about confidence intervals include:

Confidence intervals are relevant for anyone working with statistics, including:

• Misconception: A confidence interval of 95% means that there is only a 5% chance of the interval not containing the true population parameter.
• Students and educators
• Increased confidence in statistical conclusions

A margin of error refers to the maximum amount by which a sample statistic may differ from the true population parameter. A confidence interval, on the other hand, provides a range of values within which the true population parameter is likely to lie.



Conclusion

How Confidence Intervals Work

Confidence intervals provide a range of values within which a population parameter is likely to lie. They offer a way to express uncertainty about a population parameter, such as a mean or proportion, by estimating the interval within which the true parameter is likely to fall. The confidence level, usually expressed as a percentage, indicates the degree of certainty about the interval. For example, a 95% confidence interval means that if the same sample were taken multiple times, the calculated interval would contain the true population parameter 95% of the time.
