Determine whether the numerical value is a parameter or a statistic? In a phone survey of 100 random homes in a country, 21 families had garages.
Is this a parameter because the data set of 100 random homes is a population?
Is this a statistic, because the data set of 100 random homes is a sample?

PsyDAG,
Parameters are measures on the total population that you are considering (all the subjects have been measured), while statistics are measures on a portion of the population.
Would you be generalizing to all homes in that country?
