Content: Factors That Affect Confidence Intervals
The width of a confidence interval could be either narrow or wide. If we look at the confidence interval formula, we can see several factors that can impact the confidence intervals. It’s vital to have narrower confidence intervals as you can gain more information about a population parameter with it. Let’s look into some factors that affect a confidence interval inversely or directly. Size of Sample
In the confidence interval formula, the size of the sample is represented with n. The sample size works indirectly with a confidence interval; as the size of the sample increases, the confidence interval decreases, and vice. However, all of the other values should remain the same. A bigger sample size generates more reliable results as it has more information about a population parameter. Confidence Level
The confidence interval increases as the confidence level are increased while all of the other factors are fixed. It’s essential to reduce the margin of error, and that’s only possible by improving the quality of data and using a higher confidence level.
