Which of the following does not illustrate randomization?
A. using a random number generator to assign subjects to groups
B. using students in intact classrooms as members of groups
C. using the results of a name draw to assign subjects to groups
D. using the results of a coin toss to assign subjects to groups
This is the answer because the other choices are using a count toss, or generator, something random unlike B, which is just using certain students as part of the group.
