Research findings suggest that background music can affect cognitive focus during problem solving. To test this, a researcher conducted an experiment under the following conditions:
The order of conditions was counterbalanced, and both conditions were completed on the same day.
In order to produce the two puzzle sets, a pool of 40 logic puzzles was identified. These were allocated to two puzzle sets of equal length (20 puzzles each) by a process of randomisation.
Explain how randomisation could be used to allocate the 40 logic puzzles to Puzzle Set A and Puzzle Set B.
