Confidence Interval For The Population Mean Score Excel Sheets The CONFIDENCE function calculates the confidence interval for the mean of the population Typically people use a confidence level of 95 for most of their calculations This means that there is a 95 probability the population mean would fall
Excel offers a few ways to derive the confidence interval for a population mean First we ll show you how we can use the CONFIDENCE function and other statistical functions to compute the confidence interval manually We can also use the Analysis Toolpak add in to find the confidence interval of a given population The Confidence Interval for the population mean is 105 17 95 or simply 87 05 122 95 Calculate Confidence Intervals Using Descriptive Statistics Another alternative method of calculating Confidence Intervals in Excel is by using Descriptive Statistics feature This feature is located in the Data Ribbon Data Analysis
