FRAME 20. (Continued)
you went to dinner at that fancy restaurant and pronounced their food 'excellent," you were
asking a statement based on a sample of only one meal about the population of all meals that
had keen, or will be, prepared at that restaurant.
If we have a small population, say an infantry platoon and we are interested in average age,
we could take a census. The value we compute as the average age is called a PARAMETER. In
general, a parameter is a value that can computed fro a population if the entire population is
However, the entire population is often not available. So, we use a port of the population
( sample) to compute an ESTIMATE of the population value. This estimate, computed from a
sample, is called a STATISTIC.
Now would you summarize this relationship? The________________________________
is the whole; the _______________________ is a part of the whole.
The ________________________________ is the true value computed from the population;
the _________________________________is the estimate of this value computed from the
