For Example: Let s say that you ve got 50 people in your neighborhood, and you want to draw a simple random sample of eight of your neighbors, n=8, to survey about their perception of living conditions in the neighborhood. Your target population (population-of-interest) is the 50 people in the neighborhood. You make a list of the 50 people and number each person in the list 1 through 50.

Then I press the “ L3 ” key, [ 2nd ] [ 3 ]. 10. Then I press [ ENTER ]. 11. When I go to [ STAT ] [1:Edit ], I have a much more “ readable ” listing of the random numbers. So the 8 people selected for the survey are persons numbered 50, 11, 40, 48, 12, 19, 1, 47. I hope that this helps. dj ``````````````````````````````````````````````````````````````...
