Professor Montando is carrying out a memory experiment where he assigns undergraduate research participants to one of four different study conditions: one condition where they receive 1 minute to study a word list, one with 2 minutes of study time,

one with 4 minutes, and one with 10 minutes. He writes these conditions on four separate slips of paper, puts them in a hat and, as subjects arrive for the study, he picks out a slip of paper and assigns each subject to one of the four conditions until all four slips of paper have been selected. At this point, he puts all four slips back into the hat and repeats this procedure until all subjects have been assigned. This procedure is referred to as a. block random assignment. b. random selection. c. simple random assignment. d. stratified random assignment.
