A comparison between the phone length derivative and base value (see Section 5.1) correlations with depression rating. Derivative correlations are marked with a cross; base value correlations are marked with a circle. Blue indicates a positive correlation, red a negative one. The size of the marker is scaled by the magnitude of the correlation. Only significant correlations (p-value < 0.05) are shown. Correlation coefficient range: max cross marker = 0.40; min cross marker = 0.21.
