Simple random sampling (give numbers to clients, pick a random technique to go through numbers and pick those that match the technique (ex. All numbers are 6 digit; go through the middle 3 digits to find those that are less than 100) each person is treated as a whole and have equal opportunity of being selected; being picked from a hat.
