Veelgestelde vragen
What is Pearson correlation?
Pearson correlation is a statistical measure that quantifies the linear relationship between two variables, ranging from -1 to +1. A value near 0 means no linear relationship. Here it measures how strongly your sleep hours relate to your mood.
How many days of data do I need for accurate results?
This tool uses 7 days, which gives a useful initial estimate. For statistically robust results, 30+ days of data is ideal — which is exactly what tr8ck does automatically when you log daily.
Does more sleep always mean better mood?
Not necessarily. Sleep quality matters more than quantity. Both too little and too much sleep can negatively affect mood. Most adults function best with 7-9 hours of quality sleep.
What other factors affect mood besides sleep?
Many factors influence mood: exercise, nutrition, social connection, stress levels, sunlight exposure, medication, hormonal cycles, and screen time. tr8ck tracks multiple metrics to find your strongest correlations.
