A researcher conducted an experiment to investigate the effect of background music on reading comprehension. Student volunteers were tested on their comprehension scores before and after a study session under one of two conditions: Group 1 (Background Music) or Group 2 (Silence).
Figure 1
| Group | Pre-session comprehension score | Post-session comprehension score |
|---|---|---|
| Group 1 (Background Music) | 12 | 15 |
| Group 2 (Silence) | 12 | 18 |
Explain how the researcher could allocate the student volunteers randomly to the two conditions of the experiment.
