Foot Lengths of Women: The given data represents foot lengths (in inches) of randomly selected women.
Sample Year: The data was collected in 1988.
Mode: The mode is 9.2 inches.
Midrange: The midrange is 9.2 inches.

Current Population: The statistics from 1988 may not represent the current population of all women in the military. Past data usually isn't directly representative of the present.
Random Sample: The sample may still be considered representative if it is a random sample and substantial in size (greater than 10, in this case).
Gender Representation: The fact that the sample only includes women, and not men, suggests it is not representative of the broader population which should ideally include men, too.
Sampling Method: The method used to select the women in the sample is important. If the selection was not truly random, the results may not accurately represent the actual population.
