An industrial psychologist is studying the effects of adaptive active noise-cancelling headphones on cognitive fatigue during intense software programming tasks. There are 150 software developers participating in the study. The researcher assigns the first 75 developers who register for the study to Group A and the remaining 75 developers to Group B.
The researcher instructs participants in Group A to work while wearing adaptive active noise-cancelling (ANC) headphones over a five-day work period.
The researcher instructs participants in Group B, the control group, to work while wearing passive noise-isolating headphones over the same five-day period.
Explain how random allocation could be carried out to assign the 150 participants to these two groups.
