What is Calculating Confidence Intervals in Excel about?
A confidence interval (CI) estimates the range where a true population value likely falls based on sample data, incorporating key components such as mean, standard deviation, sample size, confidence level, and margin of error. The document outlines steps to calculate CI in Excel and illustrates its application with an example related to malnutrition rates in a humanitarian context. It emphasizes the importance of CIs over p-values by providing a clearer picture of effect size and uncertainty.
