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

available.

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.

QUESTION:

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

sample.
