Tolerance Interval is also referred as enclosure intervals. It is used to compute a range of values for the fixed proportion of the population. It is likely to cover the specified or fixed proportion of the future population with a stated confidence. To generate the tolerance level, it is important to specify both minimum percentage of the population and a confidence level. Use our online tolerance interval calculator to find the enclosure interval by entering the values in all the fields.
The Tolerance interval calculator is widely used in statistical process control. The calculator finds both two-sided and one-sided tolerance interval.
