The design of experiments often requires the randomizing of subjects across conditions or the randomization of the order in which conditions are presented to a given subject. Accomplishing this task entails consulting a random number table, drawing numbers from a hat, or some other tedious method. Using a computer program to automate this task could save time. With this objective in mind, the program, RAT (Randomize And Test), was written to randomize the presentation of conditions to subjects.
RAT is a 32 bit Windows-based application developed with Microsoft Visual Basic version 6.0. The design of RAT concentrated on simplicity, ease of use, and utility. The user interface reflects these goals. It uses the random function available in Visual Basic. The random function is seeded with the current system time in milliseconds. The experimenter can save the output to a comma-delimited ASCII text file or print the output to a local or network printer using common Windows dialog boxes.
