Abstract

The paper presents a very simple introduction to the concept of confidence interval for both a proportion and a mean. The confidence interval is useful when analyzing data that refer to a sample extracted from a target population. The confidence interval defines the upper and lower values of the interval of the variable we are studying; in other words, it defines the interval that one should expect, with a predefined level of confidence, to contain the true value of the proportion or the mean value of the population.
