A confidence interval is a likelihood that a population parameter will fall between a set of values for a given percentage of the time. In a sampling procedure, confidence intervals are used to determine the degree of uncertainty or certainty. They can employ a variety of confidence levels, the most common of which are 95 percent and 99 percent. They are essentially a mechanism for rating the likelihood of something being true or false.
