A cognitive psychologist was interested in the relationship between sleep quality and cognitive processing speed. They used a correlational study to investigate this in a convenience sample of 45 undergraduate student participants.
Each participant completed a standardized sleep quality questionnaire, which yielded a numerical score out of 50. The participants' cognitive processing speed was then measured by recording the average time in seconds taken to complete a computerized choice-reaction-time task across 10 trials.
Explain why the data collected in this study is an example of quantitative data.
