A researcher wants to investigate whether there is a correlation between weekly screen-time on mobile devices and sleep quality in teenagers.
She selects a sample of 20 participants.
She wants to avoid using subjective self-report methods (such as estimated screen-time diaries or subjective sleep quality ratings) to measure both variables, aiming for more objective and operationalised measurements instead.
Suggest how the researcher could measure and operationalise the two co-variables, weekly mobile screen-time and sleep quality, for this study.
