A sports psychologist is investigating the relationship between physiological arousal and motor skill accuracy under pressure. They conduct a correlational study using a sample of 30 semi-professional basketball players.
Physiological arousal is measured by recording each participant's heart rate in beats per minute (bpm) immediately before they perform a task. Motor skill accuracy is measured by counting the number of successful free throws completed out of 20 attempts.
Explain why the data collected in this study is an example of quantitative data.
