Small confidence interval meaning
Webb1 apr. 2010 · Defining a CI A good way to think about a CI is as a range of plausible values for the population mean (or another population parameter such as a correlation), calculated from our sample data (see Figure 1). A CI with a 95 percent confidence level has a 95 percent chance of capturing the population mean.
