Label Here you can compute an estimate for the confidence interval of the mean and variance for your data. It is used a statistical technique called 'empirical bootstrap'. This is a non-parametric method, therefore it works for normal and non-normal data. Typical applications are:

1 / 3
You measured the transaction time of your process and now you would like to know the 95% condidence interval of the mean transaction time.
2 / 3
As a supervisor of an administrative process, you developed a different method to perform a task. Now you wish to know the confidence interval for the original and new method.
3 / 3
You measured the interarrival time at a supermarket cashier. Now you wish to know the interval that has the actual mean with 95% statistical confidence.
