Describe a parameter of interest
WebA specific confidence interval gives a range of plausible values for the parameter of interest. Let's look at a few examples that demonstrate how to interpret confidence … WebAn interval of values computed from sample data that is likely to cover the true parameter of interest. There are many estimators for population parameters. For example, if we want to know the "center" of a distribution, why use the mean? Could we use the median? How about using the middle value, i.e. (max+min)/2?
