sampling assures no systematic distortion, but the degree of accuracy in
representing the full distribution also depends on the number of selections
made from the distribution. As the number of selections increases, the accu-
racy improves. For example, with only 10 draws, the result may be 6males
and 4females, quite different from the underlying distribution, whereas with
1,000draws it will come much closer to 450males and 550females.
This process can be seen graphically in Figure3.5, where random selection
of a number from the range 0to 100gave the number 23. This number, 23, is
then found on the vertical axis of the ...
