Confidence intervals are also very useful for comparing means or proportions and can be used to assess whether there is a statistically meaningful difference. This is based on whether the confidence interval includes the null value (e.g., 0 for the difference in means, mean difference and risk difference or 1 for the relative risk and odds ratio).
The Excel CONFIDENCE function uses a Normal Distribution to calculate a confidence value that can be used to construct the Confidence Interval for a population mean, for a supplied probablity and sample size.It is assumed that the standard deviation of the population is known. The format of the function is:he Excel CONFIDENCE function uses a Normal Distribution to calculate a confidence value that can be used to construct the Confidence Interval for a population mean, for a supplied probablity and sample size.
