Suppose you are carrying out a randomized experiment to test whether loud music interferes with memorizing numbers. you have 20 college student participants. you want each participant to have a 50% chance of being assigned to the experimental group (memorizes numbers while music plays) and a 50% chance of being assigned to the control group (memorizes numbers with no music). let the digits 0, 1, 2, 3, and 4 represent assignment to the experimental group (music) and the digits 5, 6, 7, 8, and 9 represent assignment to the control group
