Table 1 Spearman Correlations (Rho) between monitor-determined and directly observed sitting and standing time

From: Criterion validity of the activPALTM and ActiGraph for assessing children’s sitting and standing time in a school classroom setting

Monitor Correlation (Rho) with DO
  Sitting Standing#
aP 0.86** 0.78**
AG < 13 counts/15 s (50 cpm) 0.72** 0.62**
AG < 25 counts/15 s (100 cpm) 0.76** 0.61**
AG < 38 counts/15 s (150 cpm) 0.79** 0.63**
AG < 75 counts/15 s (300 cpm) 0.80** 0.60**
  1. Note: ** = all Spearman correlations were statistically significant at p < 0.01; #Standing values for AG calculated using a count range with 200 counts/15 s (800 cpm) as the upper end cut-point and the designated cut-point as the lower end cut-point
  2. DO direct observation, aP activPal, AG ActiGraph.
