Elena carried out an experiment to investigate whether listening to background classical music affects working memory capacity.
She asked participants to complete a computerized digit span task (recalling sequences of numbers) while classical music was playing in the background.
The same participants were then asked to complete an equivalent digit span task of equal difficulty, but in silence.
Elena used a repeated measures design in her experiment.
Explain one strength and one weakness of using a repeated measures design in this study.
