... A parameter is a number that describes some characteristic of the population. In statistical practice, the value of a parameter is usually not known because we cannot examine the entire population. A statistic is a number that describes some characteristic of a sample. The value of a statistic can b ...

resampling using excel in teaching statistics
... To generate the values of a statistic for different samples using Data Table, first we calculate the value of the statistic using a random sample. This can be done using Excel random number generating functions for the appropriate population and other standard functions. This statistic value will be ...
